Abstract
Polymer reagents containing reactive functional groups are crosslinked by reacting them with compounds (crosslinking agents) which contain complimentary functional groups and have large nonlinear polarizability. The resulting polymer reagents, after poling, are useful for nonlinear optic applications. Also disclosed are the mixture which react to form the crosslinked polymer and novel crosslinking agents.
