Abstract

Provided is a polymerizable composition including an alkyne compound represented by the following general formula (1):

wherein, in general formula (1), X 1 and X 2 represent a sulfur atom, an oxygen atom, or an NH group and may be the same or different from each other, Q represents an alkylene group having 1 or 2 carbon atoms, a carbonyl group, or a thiophenylene group in which one of carbon atoms is substituted by an antimony atom, R 1 and R 2 represent an alkylene group having 1 or 2 carbon atoms and may be the same or different from each other, and m and n each represent 0 or 1.

First claim

The invention claimed is:

1. A polymerizable composition comprising an alkyne compound represented by the following general formula (1):

wherein, in general formula (1), X 1 and X 2 represent a sulfur atom, an oxygen atom, or an NH group and may be the same or different from each other, Q represents an alkylene group having 1 or 2 carbon atoms, a carbonyl group, or a thiophenylene group in which one of carbon atoms is substituted by an antimony atom, R 1 and R 2 represent an alkylene group having 1 or 2 carbon atoms and may be the same or different from each other, and m and n each represent 0 or 1, and further comprising a thiol compound.

2. The polymerizable composition according to claim 1 , comprising an alkyne compound represented by the following general formula (2) or (3):

wherein, in general formula (2), Q represents an alkylene group having 1 or 2 carbon atoms, or a thiophenylene group in which one of carbon atoms is substituted by an antimony atom, and m and n each represent 0 or 1,

wherein, in general formula (3), X 1 and X 2 represent a sulfur atom, an oxygen atom, or an NH group and may be the same or different from each other.

3. The polymerizable composition according to claim 1 , wherein the thiophenylene group in which one of carbon atoms is substituted by an antimony atom is a divalent group represented by the following Formula (4):

wherein, in general formula (4), * represents a bonding hand.

4. The polymerizable composition according to claim 1 , wherein the thiol compound includes at least one kind of polythiol compounds selected from 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, 4,8 or 4,7 or 5,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, pentaerythritol tetrakis(2-mercaptoacetate), pentaerythritol tetrakis(3-mercaptopropionate), 2,5-bis(mercaptomethyl)-1,4-dithiane, bis(mercaptoethyl)sulfide, 1,1,3,3-tetrakis(mercaptomethylthio)propane, 4,6-bis(mercaptomethylthio)-1,3-dithiane, and 2-(2,2-bis(mercaptomethylthio)ethyl)-1,3-dithietane.

5. A molded product obtained by curing the polymerizable composition according to claim 1 .

6. An optical material comprised of the molded product according to claim 5 .

7. A plastic lens comprised of the molded product according to claim 5 .
