Abstract
By reacting poly(vinyl alcohol) (PVA) with methacryloyl chloride, multimethacrylate in PVA matrix has been obtained. Free‐radical polymerization of multimethacrylate and copolymerization of two multimethacrylates in PVA and p‐cresol‐formaldehyde matrices in diluted solutions occurs probably along ordered methyl methacrylate units in the matrix and results mainly in ladder‐type homopolymer and copolymer. The structures of multimethacrylate, homopolymer, and copolymer have been found on the basis of elemental analysis, IR, and 1H NMR spectra, and examination of the products of hydrolysis.
