pH -- Ring opening metathesis polymers with cis-alpha-beta unsaturated anhydride structures for pH-responsive grafting and degradation and use thereof

摘要

The present invention relates to a novel ring-opening metathesis polymer, and more specifically, a pH-reactive ring-opening metathesis polymer prepared by ring-opening metathesis polymerization of an acid anhydride having a cis-α, β-double bond in the presence of a group's catalyst, and a drug delivery system thereof Provides such uses.
