copolyamides

基本解釋

When the content of comonomer 1010 is 20%, the water absorption is the greatest in the copolyamides.
含量低時(shí)，共聚物密度小於計(jì)算值.;尼龍1010含量20%25左右時(shí)，共聚物具有較大吸水率
In this paper, the stability of copolyamides prepared from p-phenylenediamine,terephthaloyl dichloride and 4, 4'-diaminodiphenylether in sulphuric acid was studied.
