Properties of copu / pmma AB crosslinked polymers

COPU/PMMAAB交联聚合物的性能

Double dot half-tone : Two half-tone negatives made from the same continuous-tone copu at different screen angles are combined to make one printing plate .

双点半色调：一连续色调的原稿分别用不同网线角度造成两张半色调负片，然后合并造成一块印版。

The results show that COPU / PMMA crosslinked polymer is a semicompatible system and the compatibility reduces with the increasing PMMA content and the decreasing crosslinking density .

结果表明，COPU/PMMA交联共聚物是个半相容体系，其相容性随PMMA含量的增加和交联密度的减小而变坏。
