COMPATIBILIZED POLYESTER-POLYAMIDE BLEND

摘要

A thermoplastic resin composition comprises (A) a polyester resin, (B) a polyamide resin, (C) a modified polyolefin containing special glycidyl-bearing structural units in an amount of 10<-><4> to 10<-><2> eq/g in terms of epoxy equivalent and (D) a quaternary phosphonium salt or a quaternary ammonium salt. The glycidyl-bearing units are based on N-benzylacryl- or -methacrylamide which is substituted with a glycidyloxy group on the aromatic nuclens. By taking the above constitution, a fine homogeneous dispersion of a polyester resin and a polyamide resin with each other can be attained to give a highly heat-resistant molding material which is improved in resistance to hydrolysis as compared with the polyester resin and in water absorptivity as compared with the polyamide resin without impairing the excellent characteristics inherent in the resins.
