    摘要: The invention relates to a process for producing a polymer or copolymer from monomer material comprising an acrylate, methacrylate, or mixture of such monomers, which comprises the steps of: (a) charging into a continuous tube reactor a feedstock comprising said monomer material and a polymerization initiator; (b) maintaining a flow rate of said material through the reactor at a reaction temperature in the reactor and under pressure sufficient to provide a residence time of the feedstock in the reactor during which polymerization will occur, to form a resin product in the reactor, and said resulting resin product comprising unreacted monomer, and (c) devolatilizing said resin product exiting the reactor to remove unreacted monomers, to provide a substantially monomer-free resin product. Further, the invention relates to resin product made by the process. In particular, the invention relates to resin that has a weight average molecular weight of 10,000 or less, and a glass transition temperature of less than 0° C., preferably −20° C. or lower. The resin product of the invention is particularly useful as an additive for coating and casting resin systems.

    摘要: The use of fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of alkali metal, ammonium and/or alkanolammonium salts of optionally dihydroxy-substituted fatty acids as emulsifiers for emulsion polymerization. Excellent polymerization results are obtained despite the high linoleic acid content.
