ABSTRACT:
A thermoplastic polymer composition containing (a) a polyester or polyamide thermoplastic polymer and (b) a block graft copolymer which comprises (i) as the backbone portion at least one of a block copolymer or a hydrogenated block copolymer containing blocks of a styrene-type polymer and blocks of a butadiene-type polymer, and (ii) as the graft portion a radical disintegrative polymer, said block graft copolymer having been chemically modified with molecular units containing a functional group which will combine or interact with said thermoplastic polymer a). The thermoplastic polymer composition is superior in flexibility, resistance to chemicals and oil, impact resistance, moldability and elasticity.
