Abstract
Abstract A novel ester group-containing (meth)acrylic acid ester represented by the general formula (I): ##STR1## wherein R 1 is a hydrogen atom or a methyl group, R 2 is a C 3-20 alkylene group, R 3 is a C 1-20 hydrocarbon 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.
