Colorless, purified polymerizable composition useful for the production of crosslinked polyvinylpyrrolidone

摘要

What is provided herein is a colorless, purified polymerizable composition useful for the production of crosslinked polyvinylpyrrolidone. The polymerizable composition includes about 74-96% by weight vinylpyrrolidone monomer and 4-26% by weight of the isomeric compound 1-vinyl-3(E)-ethylidene pyrrolidone as crosslinker. The polymerizable composition is used to make crosslinked polyvinylpyrrolidone rapidly upon heating the composition at about 80 DEG -120 DEG C. in the absence of base.
