Abstract: Molding compositions are prepared from blends of (A) a thermoplastic copolyetherester elastomer; and (B) an ABS or MBS polymer. Such blends have improved ductility and chemical resistance.

Abstract: Molding compositions are prepared from blends of (A) a thermoplastic copolyetherester elastomer; (B) a styrene maleic anhydride polymer; and (C) an ABS or MBS polymer. Component B, the styrene maleic anhydride polymer may optionally contain a termonomer such as methylmethacrylate or acrylonitrile and a rubber component.

Abstract: A bonded reinforced plastic structure which comprises reinforced plastic parts of sheet molding compound or bulk molding compound, coated with a primer coat and bonded together with a thermoplastic block copolymer. The primer coat comprises an epoxidized novolac resin and a resinous amidopolyamine. The block copolymer comprises from 40 to 80 weight percent crystalline polyester or polyamide segments and 20 to 60 weight percent amorphous polyamide or polyether segments and has a crystalline melting point of at least 155.degree. C. The bonded structure is adapted to survive the hot environment of paint curing ovens.

Abstract: Molding compositions are prepared from blends of (A) a thermoplastic copolyetherester elastomer; (B) a styrene maleic anhydride polymer; (C) an ABS or MBS polymer; and (D) a nitrile rubber. Component B, the styrene maleic anhydride polymer may optionally contain a termonomer such as methyl-methacrylate or acrylonitrile and a rubber component.
