23 Jul NOVEL POLYMER CONTAINING PHOSPHATE GROUP AND PRODUCTION THEREOF
Abstract
PURPOSE:To industrially easily obtain the titled novel polymer usable widely in fields such as engineering, medicine, etc., having surface active ability, self tissue properties and high safety to human body, obtained by polymerizing a specific phosphoric ester monomer. CONSTITUTION:A monomer shown by the formula I [R1 is H or methyl; R2 is 1-36C alkyl; M is H, alkali (earth) metal, etc.,] is polymerized in the presence of a polymerization initiator such as diisopropyl peroxydicarbonate, etc., preferably at 20-80 deg.C to give the aimed polymer consisting of a repeating unit shown by the formula II. The monomer shown by the formula I, for example, is obtained by reacting a high-purity phosphoric monoester alkali metallic salt with glycidyl (meth)acrylate. The amount of the polymerization initiator used is preferably 0.05-5wt% based on the monomer.
