Provided are articles such as medical devices which comprise at least one water soluble, crosslinked copolymer. The primary polymer chains of the copolymer are hydrophilic and independently have a degree of polymerization in the range of about 10 to about 10,000. The water soluble, crosslinked copolymers of the present invention are free from terminal substrate associating segments. The copolymers may be incorporated into a formulation from which the article is made or may be contacted with the article post-formation.
本文所提供的物品,如医疗器械,包含至少一种水溶性交联共聚物。共聚物的主聚合物链是亲水性的,其聚合度在约 10 到约 10,000 之间。本发明的水溶性交联共聚物不含末端基质连接段。本发明的共聚物可以加入制造物品的配方中,也可以在物品成型后与之接触。
