Novel polymer containing cyclopentanylvinylene units |
摘要 |
Processes for preparing novel polymers containing carboxyl or carboxylate groups which comprises hydrolyzing starting polymers containing acid anhydride groups in the presence of acids or alkalies, the starting polymers being prepared by ring-opening polymerization of acid anhydride-type norbornene derivatives, and the characteristics and utility of these novel polymers are disclosed. |
