摘要
在聚乙烯醇与甲醛的缩合反应过程中,加入少量有机聚合物使之接技共聚,并辅以功能性助剂所制得的改性聚乙烯醇缩醛胶,其粘结强度明显提高,应用范围更广,而成本增加甚微。
In the process of condensation reaction of polyvinyl alcohol with formaldehyde, modified polyvinyl formal adhesive can be prepared with an addition of a few of organic polymer for graft copolymerization and functional auxiliary agents so as to remarkably improve its bond strength and extend its application range with just a little bit of cost price increase.
