Intermacromolecular complexes by in situ polymerization

摘要: Abstract Hydrogen-bonded complexes of poly(acrylic acid) and poly(ethyl oxazoline) (PEOx) were prepared by photopolymerization acrylic acid in which PEOx was dissolved. The glass transition temperatures ( T g ) the are not only higher than those blends but also value either component polymer. dissolve strong proton-accepting solvents like dimethyl formamide or sulphoxide (DMSO), swollen to various degrees water methanol, resistant swelling dioxane. When density hydrogen bond donor groups chain is reduced 50% with use a copolymer methyl methacrylate, intermolecular association still takes place, although affinity complexation some extent. interpenetrating networks (semi-IPNs) this method, about half can be extracted DMSO after 4 days. incomplete removal probably result topographical constraints against diffusion.
