The fraction of carbonyl groups bound by H-bonds in aqueous solutions of some water-soluble polymers has been determined, using a method based on the previously found features of changes in chemical shifts of the carbonyl carbon 13C due to substituen

The radiation grafting of N-vinylpyrrolidone inside crazes provides a means for introducing a large quantity of polyvinylpyrrolidone into crystalline PET and for uniform distribution of the polyvinylpyrrolidone over the thickness of the film. The pol
