摘要： 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.
摘要翻译：根据透射电子显微镜（TEM）显微照片，聚酯（例如聚对苯二甲酸乙二醇酯（PET））和含有有效量的聚酯增容剂和聚碳酸酯增容剂的聚碳酸酯的相容合金不表现出任何明显的相分离。 PET增容剂是期望具有柔性聚合物芯和功能性聚合物壳的多相聚合物。聚碳酸酯增容剂也是期望具有柔性聚合物芯和功能聚合物壳的多相聚合物。任选地，可以使用与合金不相容的聚合物，例如不混溶的聚酯，例如聚对苯二甲酸丁二醇酯（PBT）。换句话说，不相容的聚酯可以与相容的合金聚酯一起使用。该合金是热塑性的并且可以包含各种填料以及各种增强纤维如玻璃纤维。该合金具有出人意料的改进的性能，例如非常高的缺口伊佐德冲击强度，高热偏转等，因此易于加工并具有用于汽车等的外部车身面板的用途。
