ABSTRACT:
Cyclic polyamide oligomers are prepared by the reaction of various spirobiindane diamines, including spirobiindane bisphenol bis-aminophenoxy ethers, with dicarboxylic acid chloride such as isophthaloyl chloride. The oligomer compositions may be converted to copolyamides by reaction with lactams in the presence of basic reagents.
