Preparation of modified polymers of N-vinylpyrrolid-2-one and their use for the preparation of polymers interrupted by bridge members |
摘要 |
A process for the preparation of modified poly-N-vinylpyrrolid-2-one containing two identical reactive groups, wherein polyvinylpyrrolidone is treated with complex hydrides, with or without further reaction of the modified polyvinylpyrrolidone with a reactive bifunctional compound, to give a polymer which has a molecular weight at least 2.5 times as great as that of the starting polymer.
