Abstract
The present invention provides a (meth)acryloyl-group-containing carbamoyl halide represented by the following formula (1): where R1 represents a hydrogen atom or a methyl group; R2 represents a linear or branched C1-C10 alkylene group; R3 represents a C1-C5 alkyl group; and X represents a halogen atom. The present invention also provides a production process for the halide.
Claims11
A process for producing a (meth)acryloyl-group-containing carbamoyl halide represented by the following formula (1):
- wherein R1 represents a hydrogen atom or a methyl group;
- R2 represents a linear or branched C1-C10 alkylene group;
