Ester groups containing (Meth)acrylic acid ester, their (Co-)polymers, their (Co)polymer-containing composition and their (Meth)acrylic acid-ester-containing composition.

摘要

A novel ester group-containing (meth)acrylic acid ester represented by the general formula (I): CHEM wherein R1 is a hydrogen atom or a methyl group, R2 is a C3-20alkylene group, R3 is a C1-20hydrccarbon group or its derivative, and l is an integer of 1-20, and a (co)polymer composed of said ester group-containing (meth)acrylic acid ester and other monomer(s) copolymerizable therewith. This (co)polymer gives a crosslinked product superior in heat resistance, low-temperature resistance and oil resistance.
