Abstract: The invention pertains to a thermoplastic halogenated polymer composition comprising: at least one thermoplastic halogenated polymer (A); and less than 30% by weight of (A) of fused silica particles having a BET (N2) surface area of at most 50 m2/g (B). The invention also relates to a process for manufacturing the thermoplastic halogenated polymer composition, to the use of fused silica particles as impact modifier, and to the articles therefrom. Preferably the thermoplastic halogenated polymer is a semi-crystalline fluoropolymer.

Abstract: A weather resistant coating composition comprising a miscible polymer blend of highly crystalline polyvinylidene fluoride polymer and polyalkyl methacrylate, such as PVDF and PMMA. The miscible blend comprises from about 50 weight percent to about 90 weight percent polymer comprising polyvinylidene fluoride and from about 10 weight percent to about 50 weight percent polyalkyl methacrylate. The polyalkyl methacrylate having a molecular weight within the range of about 25,000 grams per mole to about 200,000 grams per mole. The crystallinity of the polyvinylidene fluoride polymer is about 20% to about 70%. The weather resistant coating has excellent and unexpected physical characteristics, including solvent resistance and gloss retention.
