Abstract: Sterically hindered amine groups were incorporated into poly(methyl methacrylate) and poly(ethyl methacrylate) by copolymerizing 2,2,6,6 tetramethylpiperidinyl methacrylate (TPMA) with MMA and EMA. The replacement of the pendant alkyl groups of the polymethacrylates by SHA groups reduced their miscibility with poly(styrene-co-acrylonitrile) (SAN) and with poly( alpha -methyl styrene-co-acrylonitrile) (MSAN). The cloud points of the miscible blends indicated that the effective interaction parameter B of a blend became less negative with increasing TPMA content in the copolymer, and B was more negative for SAN blend than for a corresponding MSAN blend.
