Polyalkoxyalkyl (meth)acrylates and preparation thereof

摘要

To provide a biocompatible material with a high level of safety at a low cost. The biocompatible material has a polymer synthesized from monomers by an anionic polymerization, wherein the polymer has a ratio (Mw/Mn) of a weight-average molecular weight (Mw) to a number-average molecular weight (Mn) in a range of 1.0 to 1.5, in which the weight-average molecular weight is 40,000 or more, and each of the monomers is represented by a following general formula (1): where R<1> is a hydrogen atom or a methyl group; R<2> is a C1-C4 alkylene group; and R<3> is a C1-C4 alkyl group. The anionic polymerization may proceed in the presence of a tertiary aluminium compound.
