Abstract

A polymerizable composition of the present invention includes a polymerization reactive compound (A), and an internal release agent (B) including a polyether-modified silicone compound (b1) represented by General Formula (1) and a polyether-modified silicone compound (b2) represented by General Formula (2), in which the polymerization reactive compound (A) is one or more compounds selected from a polyiso(thio) cyanate compound, a poly(thio) epoxy compound, a polyoxetanyl compound, a polythietanyl compound, an alkyne compound, a poly(thi)ol compound, a polyamine compound, an acid anhydride, or a polycarboxylic acid compound.

First claim

The invention claimed is:

1. A polymerizable composition comprising:
a polymerization reactive compound (A); and
an internal release agent (B) including a polyether-modified silicone compound (b1) represented by General Formula (1) and a polyether-modified silicone compound (b2) represented by General Formula (2),
wherein the polymerization reactive compound (A) is one or more compounds selected from a polyiso(thio)cyanate compound, a poly(thio)epoxy compound, a polyoxetanyl compound, a polythietanyl compound, an alkyne compound, a poly(thi)ol compound, a polyamine compound, an acid anhydride, and a polycarboxylic acid compound,

wherein, in Formula (1), m and n may be the same as or different from each other, and represent an integer of 1 or more; a and b may be the same as or different from each other, and represent an integer of 0 or more, provided that a case where both of a and b are 0 is excluded; and R 1 represents a linear or branched alkyl group having 1 to 6 carbon atoms or a hydrogen atom,

wherein, in Formula (2), p is an integer of 1 or more; c, d, e, and f may be the same as or different from each other, and represent an integer of 0 or more, provided that a case where all of c, d, e, and f are 0 is excluded; and R 2 and R 3 may be the same as or different from each other, and represent a linear or branched alkyl group having 1 to 6 carbon atoms or a hydrogen atom.

2. The polymerizable composition according to claim 1 ,
wherein the polymerization reactive compound (A) is a combination of two compounds selected from a poly(thio)epoxy compound, an acid anhydride, a polyiso(thio)cyanate compound, and a poly(thi)ol compound.

3. The polymerizable composition according to claim 1 ,
wherein the internal release agent (B) is included in the amount of 1×10 −1 to 5×10 4 ppm with respect to the polymerization reactive compound (A).

4. A molded product formed by curing the polymerizable composition according to claim 1 .

5. An optical material comprising:
the molded product according to claim 4 .

6. A plastic lens comprising:
the molded product according to claim 4 .

7. A process for producing a plastic lens, comprising:
a step of cast-polymerizing the polymerizable composition according to claim 1 .
