ABSTRACT:
It is an object of the present invention to provide a vinyl ether group-containing, (meth)acrylic ester, which has both radical polymerizability and cation polymerizability, improved in storage stability and stability in handling without impairing its polymerizability or, in other words, provide a stabilized vinyl ether group-containing (meth)acrylic ester. Another object is to provide a method of producing a stabilized vinyl ether group-containing (meth)acrylic ester composition. A further object is to provide a method of stably handing, a method of economically and stably producing and a method of purifying a vinyl ether group-containing (meth)acrylic ester.A vinyl ether group-containing (meth)acrylic ester composition which comprises a radical polymerization inhibitor and a vinyl ether group-containing (meth)acrylic ester represented by the following general formula (1):in-line-formulae description="In-line Formulae" end="lead"?CH2=CR1-COO—R2-O—CH—CH—R3 (1)in-line-formulae description="In-line Formulae" end="tail"?in the formula, R1 represents a hydrogen atom or a methyl group, R2 represents an organic residue and R3 represents a hydrogen atom or an organic residue.
