标 题:Synthesis of multi-functional hyperbranched polymers by polymerization of di-or tri-vinyl monomers in the presence of a chain transfer catalyst
发明人：GUAN ZHIBIN
权利人:DU PONT
摘要:This invention concerns the synthesis of multi-functional hyperbranched polymers by free radical polymerization of di- or tri-vinyl monomers in the presence of a chain transfer catalyst and a non-peroxide free radical initiator. The low viscosity and high functionality of these polymers make them useful for automotive coatings and for photopolymerization applications.

标 题 :Marine antifouling paint based on silyl acrylate copolymer synthesis

摘要:This invention involves the production of marine anti-fouling paint using the synthesis of silyl acrylate copolymers. One of the most effective anti-algae or anti-fouling paints was self-polishing paints based on acrylate resins containing tributyl tin, which were banned due to the toxicity of their tin compounds. One of the best-introduced alternatives is self-polishing paints based on silyl acrylate copolymers, but their performance is subpar and they have a shorter lifespan. In this invention, silyl acrylate copolymers in a controlled structure, including at least one soft monomer such as butyl acrylate, ethyl acrylate, etc., at least one hard monomer such as methyl methacrylate, 2-methoxyethyl methacrylate, etc. and at least one functional monomer such as triisopropyl silyl acrylate, triisopropyl silyl methacrylate, tertiary-butyl dimethyl silyl methacrylate, and tri-N-butyl silyl methacrylate were synthesized in which monomers or hard monomers were gradually added to the reactor in 2-6 hours.

摘要:A method for the synthesis of acrylic resin by means of a radical reaction comprises: a loading and activation step that provides mixing and gradual heating of methyl methacrylate, one or more thermal initiators such as azobisisobutyronitrile and one or more mercaptan chain transfer agents in a discontinuous production reactor, in order to obtain a homogeneous mixture, a reaction step that provides incubation of the reaction, including stopping the mixing and maintaining the heat of the mixture and completion of the reaction with low-rpm regimen stirring of the mixture, and a cooling step that provides cooling and stirring of the homogeneous mixture to obtain a casting acrylic resin.
