ABSTRACT:
Novel polyamides are prepared having end groups especially selected to impart special properties to the polymer. These polyamides are prepared by utilizing anionic polymerization processes and the end groups can be of a type that, under existing methods, normally will hinder or completely stop the anionic polymerization reaction. The hindering effect of these end groups is largely overcome through the formation of novel initiator compounds that enables the polymerization reaction to proceed with extreme rapidity at comparatively low temperatures despite the presence of these end groups.
