    • 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.
    • 本发明涉及由包含丙烯酸酯,甲基丙烯酸酯或这些单体的混合物的单体材料制备聚合物或共聚物的方法,其包括以下步骤:(a)将连续管式反应器装入包含所述单体材料的原料和 聚合引发剂; (b)在反应器中的反应温度和足够的压力下保持所述材料通过反应器的流速,以提供原料在聚合反应期间的停留时间,以便在反应器中形成树脂产物, 并且所述得到的树脂产品包含未反应的单体,和(c)使离开反应器的所述树脂产物脱挥发分以除去未反应的单体,以提供基本上不含单体的树脂产物。 此外,本发明涉及通过该方法制备的树脂产品。 特别地,本发明涉及重均分子量为10,000以下,玻璃化转变温度低于0℃,优选为-20℃以下的树脂。 本发明的树脂产品特别可用作涂料和浇铸树脂体系的添加剂。
