Abstract
A cross-linkage polymeric casting composition including an effective amount of a divinyl ester monomer of a bicyclic or polycyclic compound, and optionally, a minor amount of a di- or polythio compound. The specification and claims include allylic ethers withing the definition of divinyl ester, for example bisphenol fluorene diglycidyl allylic ether and bisphenol S diallyl ether.
Claims19
A cross-linkable polymeric casting composition including an effective amount of a divinyl ester monomer selected from compounds having the formula ##STR21## wherein G is selected from the group consisting of ##STR22## M is selected from the group consisting of a bond, ##STR23## --S-- methylene and --CH.sub.2 --S--CH.sub.2 --R.sub.1, R.sub.2, R.sub.3 and R.sub.4 which may be the same or different, are selected from the group consisting of hydrogen and alkyl of 1 to 6 carbon atoms,
- n is an integer having a value of 0 to 10,
- Y is hydrogen or a halogen;
- and
- J is an unsaturated terminal group selected from allyl and the group of formula ##STR24## where R.sup.5 is hydrogen or C.sub.1 to C.sub.6 alkyl, and optionally a minor amount of a di- or polythio compound.
