Abstract:
1. A monocomponent-molded composition of a blend consisting essentially of a soft thermoplastic copolyether ester elastomer and a hard polyester resin reinforced with a fibrous or particulate filler, the molded composition having an inhomogeneous structure comprising an inner part and a surface part, the surface part being rich in the elastomer and poor in the polyester resin and the reinforcing filler compared to the inner part, said composition being obtained by monocomponent molding of a blend consisting essentially of the elastomer and the hard polyester resin wherein the elastomer comprises 20 to 70 weight percent of the total composition and has a flex modulus less than 0.1 GPa and a melting point in the range 155-200° C., the hard polyester resin has a flex modulus of at least 2.0 GPa and a melting point in the range 210-230° C., and only the hard polyester resin is reinforced with the particulate filler.
