  • Publication number: 20030073771
    Abstract: The present invention relates to a process for improving the shelf life of a hindered phenol antioxidant comprising the step of intimately mixing the hindered phenol antioxidant with a sulfur-containing peroxide decomposer. The inventors have discovered that mixing the peroxide decomposer with the hindered phenol antioxidant reduces the tendency of hindered phenols to yellow with age. This increases the desirability of the hindered phenol because it will not impart color to polymer systems. The present invention also relates to a composition produced from the process described above, and stabilized compositions and additive packages containing the composition produced from the above-described process.

  • Patent number: 5322875
    Abstract: A polyvinylbutyral-based thermoplastic composition which is useful for forming thermoadhesive films for adhering bases onto a glazing. The composition comprises a polyvinylbutyral resin with a hydroxyl group content of between 22 and 26% by weight, a plasticizer for the resin and an orthosubstituted phenolic antioxidizing agent. This composition is useful for forming a thermoadhesive film having good adhesion at the surface of the glass and good stability at high temperatures.

  • Patent number: 5159003
    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.
