The terpolymers of the invention: (a) a vinyl lactam, such as vinyl pyrrolidone or vinyl caprolactam;
发明的三元：（一）一乙烯基酰胺，如聚乙烯吡咯烷酮或乙烯基己内酰胺；
2
The results showed that the terpolymers possessed good emulsifying property and water absorbency , and behaved as thermoplastic elastomers according to their composition.
结果表明，合成的共聚物具有良好的乳化性及吸水性，并在一定组成下呈现热塑性弹性体的性质。
3
The experimental results show that ammonium persulfate-sodium hydrogen sulphite redox initiation system is the most appropriate for the preparation of DMC/AM/AA terpolymers.
