I understand that examples are found among the polyolefins, poly(vinyl ethers), poly(alkylene oxides), poly(methyl acrylates), poly(chloral), and polysaccharides, but I am looking for cited references in the literature. I appreciate any suggestions. Bill Welsh Dept of Chem. Univ. of Missouri-St. Louis
