    • The present invention provides a method for producing an (meth)acrylate syrup by bulk polymerization which is characterized by: a) using (meth)acrylate ester monomer; and b) using 2,4-diphenyl-4methyl-1-pentenol singly or together with a thiol chain transfer agent as a chain transfer agent, c) initiating polymerization by adding an initiator having the half-life of up to 30 minutes at 55-80° C. of initial reaction temperature, so as to maintain the peak reactor temperature below 95° C. and the reactor conversion rate as 5-50 weight %. The method for producing an (meth)acrylate syrup of the present invention has such advantages that reaction runaway does not occur, the control of molecular weight and conversion rate is possible even at low exothermic temperature without stirring failure, and a partially polymerized (meth)acrylate syrup can also be prepared therefrom.
    • 本发明提供通过本体聚合制备(甲基)丙烯酸酯糖浆的方法,其特征在于:a)使用(甲基)丙烯酸酯单体; 和b)使用2,4-二苯基-4-甲基-1-戊烯醇单独或与硫醇链转移剂一起作为链转移剂,c)通过在55℃下加入具有长达30分钟的半衰期的引发剂来引发聚合 -80℃的初始反应温度,以保持峰值反应器温度低于95℃,反应器转化率为5-50重量%。 本发明的(甲基)丙烯酸酯浆料的制造方法具有不发生反应失控的优点,即使在没有搅拌失效的低放热温度下也可以控制分子量和转化率,部分聚合的(甲基) 丙烯酸酯糖浆也可以由其制备。
