Abstract: The present invention provides a thermoformable polymer blend that resists surface discoloration when exposed to acidic environments, such as exist within a clothes treating apparatus having an interior region into which is introduced a conditioning composition comprising from about 0.001% to about 10% of a diethylene glycol, from about 0.01% to about 10% of a beta cyclodextrin, from about 0.001% to about 5% of a surfactant, from about 0% to about 2% of a preservative, and the balance water. The discoloration resistant thermoformable polymer blend according to the invention includes: (A) a polymer package including a blend of: (Ai) one or more homopolymers and/or copolymers of polypropylene; (Aii) one or more polymers of vinyl aromatic monomers; (Aiii) one or more block polymers; and (Aiv) one or more styrene-maleic anhydride copolymers; (B) a surface treated mineral filler; (C) an antioxidant package; (D) a zinc-based lubricant; and (E) optionally, a titanium dioxide based colorant system.

Abstract: The present invention provides a polymer alloy including from about 40% to about 75% by weight of at least one polyamide, from about 10% to about 50% by weight polypropylene, from about 0.01% to about 1.0% by weight of at least one block copolymer including a vinyl aromatic monomer and a conjugated diene, and also includes an unsaturated dicarboxylic reagent, from about 0.1% to about 5.0% by weight of at least one block copolymer or terpolymer, wherein the terpolymer may have an unsaturated dicarboxylic reagent grafted thereto, from about 0.01% to about 7.5% of a compatibilizing agent, and from about 5% to about 50% by weight of a filler. The alloy of the present invention exhibits improved knitline strength and improved drop impact results compared with prior art fiberglass-reinforced nylon blends.
