化学改性的常用：一种是以被改性的树脂单体为一元，改性单体为另一元，在反应釜内进行接枝共聚并新的共聚物；第二种是将被改性树脂作为主要原料，通过树脂分子中的极性元素对其进行有效的改性。
The common methods of chemical modification are: one is one element of the modified resin monomer, the modified monomer is another, graft copolymerization in the reaction kettle and a new copolymer. The second method is to modify the modified resin as the main raw material by increasing the polar element in the resin molecule.
