✦ Synopsis

Copolymers of phenylacetylene (PA) and p-nitrophenylacetylene (pNPA) with various monomers ratios were prepared and characterized. The solubility of copolymers is dependent on the number of PA units in the chain. They show a good degree of stereoregularity and the M W s are in the 10 3 -10 5 a.m.u. range, depending on the monomers and catalyst molar ratios. The soluble samples exhibit film-forming properties and the film-surface morphology may be varied by using different solvents. The copolymers give good electrical response to relative humidity variations.

Copolymers including hydroquinone and vinylpyridine units have been prepared by the copolymerization reaction of quinones with vinylpyridines. By-products of these reactions are the homopolymer and the hydroquinone form of the respective quinone. It has been established that in the formation of the

Polyurethane polymers are a wide class of materials, ranging from surface coatings and adhesives to flexible or rigid foams. However, polyurethanes in general are very flammable and produce heavy smoke when burning. As a result of their flammability, there is a great interest in the development of m
