Claims
- 1. A curable composition which consists essentially of:
- (a) a maleimide of formula I ##STR6## wherein R denotes an n-valent aliphatic or aromatic radical and n denotes the number 2;
- (b) 2,2,4-trimethyl-1,2-dihydroquinoline; in such ratio that for 1 imido group equivalent of component (a) is used 0.05 to 1 mole of 2,2,4-trimethyl-1,2-dihydroquinoline (b); and
- (c) a copolymerizable compound having at least one polymerizable, olefinic double bond, in an amount up to 50% by weight, relative to the total weight of components (a) plus (b).
- 2. A composition according to claim 1 wherein the maleimide (a) of formula I is ##STR7## and the copolymerizable compound (c) is 3,3'-diallyl bisphenol A.
- 3. A composition according to claim 1 wherein the maleimide (a) of formula I is ##STR8## and the copolymerizable compound (c) is diallyl o-phthalate.
- 4. A composition according to claim 1 wherein R represents a bivalent aromatic radical, and n represents the number 2.
- 5. A composition according to claim 1 wherein R represents an unsubstituted phenylene radical or a phenylene radical substituted by methyl, or a radical of the formula ##STR9## wherein A represents methylene, an ether oxygen atom or sulphonyl.
- 6. A composition according to claim 1, comprising the components (a) and (b) are in such a ratio that to 1 imido group equivalent there is present 0.1 to 0.5 mole of 2,2,4-trimethyl-1,2-dihydroquinoline.
- 7. A composition according to claim 1 wherein component (c) is 3,3'-diallyl bisphenol A or o-diallylphthalate as the copolymerisable compound.
