摘要
将溶解后的聚乙烯醇溶液添加到尿素与甲醛的混合溶液中,在弱碱环境中对其进行改性聚合。称取适量的脲醛树脂预聚体加到盛有α-烯烃聚合物颗粒的容器当中,在酸性催化剂的作用下对颗粒进行包覆,为减阻剂商品化配制做出较好的前期准备。
Dissolved polyvinyl alcohol was put into the mix solution of urea and formaldehyde, and the modificated polymerization will accur in the environment of weakly alkaline. Fetch suitable urea-formaldehyde prepolymer and put it into vessel filled with α -olefin polymer particle, and coating these particles with the treatment of acidic catalyst.
