Abstract

As part of a program to further understanding of the polymerization of Nadic-Endcapped PMR systems, a series of model Norbornenyl-Imides has been synthesized and their thermal behavior explored. This paper reports syntheses and characterizations as well as their rearrangement and polymerization chemistry. Monomer isomerization at temperatures as low as 125 degree C and oligomer formation at somewhat higher temperatures have been observed. Approximate relative rates for competing isomerization pathways have been established and some information has been obtained about the details of oligomer formation. The relationship of this data to current PMR systems is briefly discussed.
