Abstract
Thermoplastic compositions are disclosed comprising a thermoplastic resin, a first impact modifier characterized by core-shell morphology and comprising a functional shell polymer, and a second impact modifier comprising a component capable of reaction with a functional shell polymer. In addition, thermoplastic compositions are also disclosed that comprise a thermoplastic resin and a loose agglomerations of particles that have open spaces, at least 50% of the loose agglomerations comprise open spaces that measure 31 to 60% by area of the loose agglomeration, and particles that are characterized by core-shell morphology. The inventive compositions demonstrate low gloss, high impact strength, good weatherability, and good flow properties.
