Blends of poly(styrene-stat-acrylonitrile) and poly(butadiene-stat-acrylonitrile) : a guide to the butadiene-acrylonitrile segmental interaction

摘要: A range of butadiene-acrylonitrile and SAN statistical copolymers were synthesized blended to establish a value for the segmental interaction energy density between butadiene acrylonitrile. Two series blends examined. In first series, «internal» form different composition found be miscible only when componsitions differed by less than about 4 vol %. contrast, with formed fairly extensive miscibility region which was analyzed considering this conic section in space
