Abstract
An addition polymer having a carbon-to-carbon backbone bearing at least two oxirane moieties per polymer molecule wherein the oxirane moieties are the reaction product of an isocyanate moiety and a glycidyl compound, such as glycidol, is readily cured to form a solid insoluble material.
Claims12
An oxirane polymer having a carbon-to-carbon polymeric backbone bearing at least two oxirane moieties per polymer molecule wherein the oxirane moieties are represented by the formula:
- ##STR4## wherein R.sup.1 is alkylene or inertly substituted alkylene and each R.sup.2 is independently hydrogen, alkyl or inertly substituted alkyl.
An oxirane polymer having a carbon-carbon polymeric backbone bearing at least two oxirane moieties per polymer molecule wherein the oxirane moieties are represented by the formula:
- ##STR8## in which R.sup.1 is a hydrogen or methyl group;
- R.sup.2 is an alkylene or inertly substituted alkylene having 2 to 6 carbon atoms;
- R.sup.3 is an alkylene or inertly substituted alkylene;
- and each R.sup.4 is independently hydrogen alkyl or inertly substituted alkyl and wherein the carbon-carbon double bond has been polymerized as part of the backbone of the polymer.
