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.
Claims14
A substantially pure compound comprising a trans-beta-isocyanatoacrylate ester in which an isocyanato functionality is directly linked to a beta-carbon in an acrylate portion of the compound, wherein said trans-beta-isocyanatoacrylate ester is iso-n-hexyl trans-beta-isocyanatoacrylate, cyclohexyl trans-beta-isocyanatoacrylate, benzyl trans-beta-isocyanatoacrylate, 2-methoxyethyl trans-beta-isocyanatoacrylate, 2-ethoxyethyl trans-beta-isocyanatoacrylate or 2-butoxyethyl trans-beta-isocyanatoacrylate.
