Abstract

본 발명은 관 내부에 스테틱믹서가 취부된 2개의 관형 반응기에 메틸메타아크릴레이트 모노머, 반응개시제 및 분자량 조절제를 첨가하여 중합시키되, 순화펌프를 통하여 반응물의 80∼95중량%가 관형반응기에서 재순환되도록 하고, 두 반응기에 각각 공급되는 열매의 온도를 조절하므로써 새로운 폴리머가 투입되는 관형반응기(A)의 온도를 85∼100℃로 조정하고 다른 관형반응기(B)의 온도는 이보다 5 내지 10℃ 높게 조정하여 중합시키는 것을 특징으로 하는 메틸메타아크릴레이트 시럽의 제조방법을 제공하는 것으로, 본 발명 방법은 종래의 괴상중합에서의 열전달 문제를 해결하였으므로 반응속도를 조절하여 원하는 중합물 함량과 시럽점도의 프리폴리머 시럽을 연속적으로 제조할 수 있는 이점을 갖는다.The present invention is polymerized by adding a methyl methacrylate monomer, a reaction initiator and a molecular weight regulator to two tubular reactors in which a static mixer is installed in a tube, and 80 to 95% by weight of the reactants are recycled in a tubular reactor through a purifying pump. By controlling the temperature of the fruit supplied to each of the two reactors, the temperature of the tubular reactor (A) into which the new polymer is introduced is adjusted to 85 to 100 ° C, and the temperature of the other tubular reactor (B) is 5 to 10 ° C higher than this. It provides a method for producing methyl methacrylate syrup characterized in that the polymerization by adjusting, the method of the present invention solves the problem of heat transfer in the conventional bulk polymerization, the reaction rate is controlled to control the prepolymer syrup of the desired polymer content and syrup viscosity Has the advantage of being able to manufacture continuously.
