  • Patent number: 11401367
    Abstract: The present invention relates to curable polyurethane polymers made from renewable materials and having polymerization accelerator groups built into the polymer. In particular hydroxylated oleaginous materials derived from plant oils, such as soybean oil, are used. These renewable materials may be formed into curable polyurethane polymers having different chemical functionalities and cure mechanisms.

  • Publication number: 20210332176
    Abstract: Curable compositions that undergo reaction induced phase separation of domains in cured matrix and provide beneficial physical and chemical properties and methods of use of such compositions. Curable compositions that undergo reaction induced phase separation of domains in cured matrix in response to a first set of curing conditions and the domains undergo a second reaction in response to a second set of curing conditions to improve the physical properties of the domains and the cured composition, such as improvements in glass transition temperature and thermal degradation.

  • Patent number: 10414845
    Abstract: A method of preparing high molecular weight poly(meth)acrylate polymers having narrow polydispersity indices (PDIs) by coupling poly(meth)acrylate building block units which themselves have narrow PDIs. The building block units have halogenated terminations, which when reacted with selected coupling agents, from the high molecular weight poly(meth)acrylate polymers.
