    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.

  • Patent number: 4826617
    Abstract: Disclosed is a new partial capping synthesis wherein resinous mixtures containing controlled amounts of phenolic hydroxyl and/or mercapto functionality, and aliphatic hydroxyl functionality are synthesized. Such synthesis comprises providing one or more resins which in total contain aliphatic primary and/or secondary hydroxyl functionality and oxirane functionality. A single resin or blend of resins may provide the requisite functionality. The one or more resins then are reacted with a carboxyl-functional capping agent bearing phenolic hydroxyl functionality and/or mercapto functionality. This reaction is conducted under reaction conditions and for a time such that the carboxyl functionality of the capping agent selectively reacts with the oxirane functionality of the one or more resins to produce a resinous product containing aliphatic hydroxyl functionality and containing phenolic hydroxyl functionality and/or mercapto functionality.
