ABSTRACT
Investigations on solution and bulk properties of grafted polymers are very often interesting for the novelty of physico-chemical topics that are usually connected with them. Solute/solvnet interaction(1), length and distribution of grafts(2), (3), phase separations are some problems concerning grafted polymers. Solution investigations frequently present a lot of difficulties for the low number of liquids in which grafted polymers are soluble. We want to report on some solution properties of a thermoplastic elastomer obtained by radical-induced grafting of styrene, S, and acrylonitrile, AN, on poly (ethylene-co-propylene), EPM, with 60% of ethylene. We have examined the influence of grafting reaction on starting EPM by GPC, the solution behaviour of some EPM-g-SAN samples by viscometry in mixed solvents and glass transition temperatures.
