✦ Synopsis

Receired 28 Not'ember 1983) AIw, tract--Vinylchloride-phenylacetylene copolymers have been prepared and characterized. A known amount of defined defect sites, t,iz. double bonds, has been introduced into the main chain of the polymer. Thermal degradation behaviour of the copolymers has been studied in trichlorobenzene solution. A strong dependence of the kinetics of dehydrochlorination and polyene formation on the defect concentration has been found. Rate constants and activation parameters have been determined. The effects of different structures have been compared.

Vinyl chloride/acetylene copolymers have been prepared under subsaturation conditions. Copolymerization rates and molecular weights of the copolymers decrease with increasing concentration of acetylene in the monomer feed, indicating that acetylene is a retarder in vinyl chloride polymerization.

The thermo reversible gelation of poly(vinylch1oride) (PVC) is investigated by calorimetric and optical measurements. In a dynamic heating or cooling scan different thermal transitions are observed. The temperatures of these enthalpic transitions as well as the gel-sol temperatures are dependent upo

The present study offers a visualization of the process of molecular aggregation in PVC polymerized at low temperatures in bulk. "Kinks" along with the chains are responsible for molecular entanglement with subsequent microcrystallization of the syndiotactic sequences. The crystallites act as bondin
