Comparative studies were made of the residue and the fraction volatile a t pyrolysis temperature, involatile a t ambient temperature obtained from polystyrene and poly(p-N,N-diethylaminostyrene) degraded under identical conditions. Poly(p-N,N-diethylaminostyrene) yielded a crosslinked glassy residue
The products obtained on vacuum pyrolysis of poly(p-N,N-diethylaminostyrene) are described. The effect of sample molecular weight and pyrolysis temperature are compared with that observed for polystyrene degraded under identical conditions. The liquid products were separated using gas-liquid chromat
## Abstract Studies have been made on the effect of the molecular weight of __p__βN,Nβdimethylaminostyrene homopolymers and the composition of its copolymers with styrene on the glass transition temperature. Comparative thermal degradation studies have been made on polystyrene and __p__βN,Nβdimethy
