Effect of microstructure on the glass transition temperature of ethylene-propylene copolymers

The fractal analysis of copolymerization processes

“…Such course of dependencies T g ( C form ) for indicated copolymers assumes different change of K M with copolymer composition. The value K M can be estimated according to the well‐known Gordon‐Tailor‐Wood equation:10 where T g 1 and T g 2 are homopolymer glass transition temperatures, W is the molar fraction of comonomer.…”
