0050/51242 Establishing the particle size of popcorn polymers during popcorn polymerization and use of popcorn polymers Abstract The particle size of popcorn polymers is established during the popcorn polymerization by a process in which reaction mixtures forming popcorn polymers and comprising monoethylenically unsaturated monomers and a crosslinking agent are polymerized in the absence of oxygen and polymerization initiators at up to 200° C. and in which the popcorn polymerization is carried out as a precipitation polymerization in water or in the absence of a solvent and the particle size of the popcorn polymers is controlled in the range from 1 &mgr;m to 10 mm by passing an inert gas stream into the reaction mixture, and popcorn polymers having a mean particle diameter of from >400 &mgr;m to 1500 &mgr;m are used as beverage clarifiers, antidiarrheal drugs and disintegration accelerators for tablets.

氧气和聚合
引发剂的情况下,将形成爆米花聚合物并含有单
乙烯基不饱和单体和
交联剂的反应混合物在高达 200° C 的温度下进行聚合。其中爆米花聚合是在
水中或无溶剂的情况下作为沉淀聚合进行的,通过向反应混合物中通入惰性气体流,将爆米花聚合物的粒径控制在 1 微米至 10 毫米的范围内,平均粒径大于 400 微米至 1500 微米的爆米花聚合物可用作饮料澄清剂、止泻药和片剂的崩解
