Abstract

Polymeric materials are disclosed herein that include a reaction product of components comprising: a) a first amine component having at least two and at most three primary amino groups, secondary amino groups, or a mixture thereof, with the proviso that the first amine component is not a silicone diamine; b) a second amine component having (i) greater than three primary amino groups, or (ii) at least three primary amino groups and a plurality of secondary amino groups, wherein the second amine component is a polymeric material having a carbon backbone or a polymeric material having a carbon backbone with a plurality of catenated nitrogen atoms; and c) an oxalate ester.
