Abstract
Novel trans-beta-isocyanatoacrylate esters, their preparation and use in forming novel polymeric compositions, including polymers useful as adhesives, are disclosed. The trans-beta-isocyanatoacrylate esters have the formula: ##STR1## wherein R is C.sub.1 -C.sub.18 linear or branched alkyls; C.sub.5 -C.sub.6 cycloalkyl; aryl; alkaryl; aralkyl; C.sub.1 -C.sub.18 halogenated alkyl; halogenated aryl; C.sub.1 -C.sub.8 alkoxyalkyl; or alkoxyaryl.
Claims9
A method of preparing and purifying a trans-beta-isocyanato-acrylate ester comprising the steps of:
- thermally decomposing a trans-beta-azidofumarate ester in the presence of an isomerization catalyst under conditions sufficient to prepare said trans-beta-isocyanatoacrylate ester in solution;
- and
- processing said solution in the presence of said isomerization catalyst to remove said trans-beta-isocyanatoacrylate ester from said solution to obtain said purified trans-beta-isocyanatoacrylate ester.
A copolymer comprising the reaction product of a trans-beta-isocyanatoacrylate ester and styrene.
A homopolymer containing a trans-beta-isocyanatoacrylate ester repeating unit.
