ABSTRACT:
A compatible alloy of a polyester, such as polyethylene terephthalate (PET), and a polycarbonate containing effective amounts of a polyester compatibilization agent and a polycarbonate compatibilization agent does not show any apparent phase separation according to Transmission Electron Microscopy (TEM) micrographs. The PET compatibilization agent is a multiphase polymer desirably with a flexible polymer core and a functional polymer shell. The polycarbonate compatibilization agent is also a multiphase polymer desirably with a flexible polymer core and a functional polymer shell. Optionally, a polymer can be utilized which is non-compatible with the alloy, such as an immiscible polyester, e.g., polybutylene terephthalate (PBT). In other words, an incompatible polyester can be utilized along with a compatible alloy polyester.
The alloy is thermoplastic and can contain various fillers as well as various reinforcing fibers such as fiberglass. The alloy has unexpectedly improved properties such as very high notched Izod impact strength, high heat deflection, and the like, and thus is readily processible and has utility as for exterior body panels for automobiles and the like.
