A new series of photoactive polymers were synthesized by condensing polymerization of different diarylidine monomers
1a,b–3a,b with 1,2-bis(chloromethylsilyl)ethane in Tetrahydrofuran and in the presence of butyllithium. These polymers
were characterized by elemental and spectral analyses. The optical properties of these polymers were comparable to
those of parent monomer units, by using ultraviolet–visible absorption and emission in solution, and they possessed the
physical characteristics of macromolecules. In addition, the thermal properties of these polymers were evaluated by thermogravimetric
analysis and DSC measurements. These polymers are thermally stable up to 207 °C except for polymer
P3a up to 180 °C and underwent degradation thereafter. The polymers exhibit glass transition temperatures lower than
0 °C except for polymer P3a where its Tg was at 35 °C. The molar masses of all polymers were determined by gel permeation
chromatography (GPC), and all polymers have high molar masses. The starting monomers 1a, 2a, and 3b were
crystallized and their structures in the crystal were determined by X-ray diffraction. The polymerizable points were found
not to be in proper spatial relation to allow for solid-state polymerization.

Novel Friedel-Crafts polyketones containing naphthalene moiety were synthesized via the electrophilic Friedel-Crafts polycondensation
method. The desired polyketones were obtained by the interaction of newly synthesized dinaphthylidenecycloalkanone
monomers with different aliphatic and aromatic diacid chlorides. The structures of new monomers and polymers were confirmed by
elemental and spectral analyses, besides X-ray single crystal data for the two new monomers. The new polyketones were characterized
by solubility, viscometry, thermal properties, scanning electron microscopy and antimicrobial activity test. All the polyketones were
soluble in formic acid as protonic solvent giving yellowish to brown colors. Some of the polyketones were partially soluble in n-hexane,
benzene and chloroform. The thermal properties of those polymers were evaluated by TGA; DTG and DTA measurements. The
desired polyketones have high thermal stability at T10 except polymer 3b which have low T10 value. FDT for all polyketones is nearly
completed at around 522–677◦C. The morphological properties of polyketone 2b were tested by SEM measurements. The synthesized
monomers and polymers were screened for their antibacterial and antifungal activities. They showed a moderated antibacterial activity
against tested Gram-negative and Gram-positive bacteria and no significant influence against the selected fungi species except
monomer 1b and polymers 2a, 3b.

A new series of heteroaromatic polyazomethines
containing 1,8-naphthyridine moieties in the
polymer backbone were synthesized with a solution polycondensation
technique. A new heteroaromatic monomer
containing 1,8-naphthyridine moieties (4-ethoxy-2,7-dicarboxaldehyde-
1,8-naphthyridine) was synthesized with an
analogous synthetic sequence and confirmed by elemental
and spectral data. The resulting polymers were characterized
by elemental, spectral analyses, solubility and viscometry
measurements. All the synthesized polyazomethines
had better solubility in polar aportic solvents. The thermal
properties of those polymers were evaluated by thermogravimetric
analysis, differential thermogravimetry, and
differential thermal analysis measurements and correlated
to their structural units. All the polymers had nearly
similar maximum polymer decomposition temperatures,
which were in the range 557–577
C. A very large difference
between the glass transitions (92–222
C) was
observed. In addition, with gel permeation chromatography,
the molecular weight determination of selected examples
of those polymers was evaluated. The values of the
average molecular weight for polyazomethines 7b and 7c
were 34,914 and 24,859, respectively. On the other hand,
the biological screening of all of the synthesized polyazomethines
was performed in variety of bacteria and fungi.
Most of the polyazomethines showed a significant influence
against Gram-negative bacteria. The minimum inhibitory
concentration of the most active polymers was
0.05 mg/mL. VC 2012 Wiley Periodicals, Inc. J Appl Polym Sci

The synthesis of high-molar-mass first- and second-generation, aromatic sulfonamide-based
dendronized polymers PG1(CH3) and PG1(NO2) as well as PG2(CH3) and PG2(NO2) has been
achieved. For PG3(CH3) at least oligomeric material could be obtained. The polymers exhibit
glass transition temperatures in the range of 135–
162 8C and are valuable components for a presently
ongoing in depth analysis of the persistence
length of dendronized polymers by SANS.
The corresponding monomers MG2(CH3) and
MG2(NO2) were crystallized and their structures
in the crystal determined by XRD. These single
crystals are the first ever obtained of dendritic
macromonomers. The polymerizable units were
found not to be in a proper spatial relation to
allow for a solid-state polymerization.

A new interesting series of linear, unsaturated copolyesters containing
cyclopentanone moiety in the main chain were synthesized by interfacial
polycondensation of a mixture containing one mole of both monomeric units 2,5-bis
(4-hydroxybenzylidene) cyclopentanone (Ia) and 2,5-bis (4-hydroxy-3-
methoxybenzylidene) cyclopentanone (Ib) together with two moles of different acid
chlorides. The yield and the values of reduced viscosity of the copolyesters were
found to be affected by the kind of organic phase, contribution of
benzyltriethylammonium chloride as a catalyst, the quantitative ratio of organic to
aqueous phase, concentration of hydrogen chloride acceptor and time of addition of
the acid chloride. The resulting copolyesters were characterized by elemental and
spectral analyses. Moreover, the various characteristics of the various types of
prepared copolymers including: solubility, viscosity, X-ray diffraction analysis, DSC
and TGA were determined and discussed. The electrical properties of the copolyesters
were tested and the morphology of selected examples of the copolyesters was
examined by scanning electron microscopy.
