Abstract
A resin composition contains one or more 2-methylene-1,3-dicarbonyl compounds. At least one of the one or more 2-methylene-1,3-dicarbonyl compounds has a molecular weight of 220 to 10,000, and the amount by weight of those of the 2-methylene-1,3-dicarbonyl compounds having a molecular weight of less than 220 relative the entire resin composition of 1 is 0.00 to 0.05. The 2-methylene-1,3-dicarbonyl compounds contain a structural unit represented by formula (I) below.
Claims19
A resin composition comprising one or more 2-methylene-1,3-dicarbonyl compounds, wherein:
- at least one of the one or more 2-methylene-1,3-dicarbonyl compounds has a molecular weight of 220 to 10,000;
- an amount by weight of 2-methylene-1,3-dicarbonyl compounds having a molecular weight of less than 220 relative to a totality of the 2-methylene-1,3-dicarbonyl compounds is 0.00 to 0.05, with an amount by weight of the totality of the 2-methylene-1,3-dicarbonyl compounds being 1;
- and
- the one or more 2-methylene-1,3-dicarbonyl compounds comprise a structural unit represented by formula (I):
- wherein the resin composition comprises at least one 2-methylene-1,3-dicarbonyl compound comprising two or more structural units represented by formula (I) and at least one 2-methylene-1,3-dicarbonyl compound having only one structural unit represented by formula (I);
- and
- wherein an amount by weight of the at least one 2-methylene-1,3-dicarbonyl compound comprising two or more structural units represented by formula (I) relative to the totality of the 2-methylene-1,3-dicarbonyl compounds is 0.05 to 0.95, with the amount by weight of the totality of the 2-methylene-1,3-dicarbonyl compounds being 1.
