标 题 :Marine antifouling paint based on silyl acrylate copolymer synthesis
发明人：LAHEGHI NEJAD FARHAD

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 subject matter of the present invention is a process for the preparation of effect compound-comprising microparticles M comprising A) the formation of a crude suspension of microparticles A by means of enzymatic polyester synthesis in an inverse miniemulsion comprising enzyme, effect compound and polyester monomers; and B) the polymerization of wall monomers from the group consisting of ethylenically unsaturated monomers, polyisocyanates and polyepoxides in the crude suspension of microparticles A. Furthermore, the present invention relates to microparticles M which can be obtained by means of the process according to the invention and also to an agrochemical formulation comprising microparticles M. In addition, the present invention relates to the use of microparticles M prepared according to the invention as component in colorants, cosmetics, drugs, biocides, plant protection agents, fertilizers, additives for food or animal fodder, or auxiliaries for polymers, paper, textiles, leather, detergents or cleaners. Finally, the invention also relates to a method for combating undesirable plant growth, to a method for combating undesirable insect or acarid infestation on plants and/or for combating phytopathogenic fungi, and to seeds treated with the agrochemical formulation.
