Notes:
A wide compositional range of copolymers of 1-cyclobutene carbonitrile (CBCN) and 1-bicyclobutance carbonitrile (BBCN) with common vinyl monomers was prepared in order to study systematically the effect of cyclobutane carbonitrile ring incorporation on the glass transition temperature (Tg). In general, the Tg's of the copolymers are increased in proportion to the weight percent of the small-ring monomer incorporated, but the 1,2-mode of incorporation raises Tg more than the 1,3-mode. Attempts were made to correlate data with quantitative Tg-composition relationships (Fox-Johnston equations). Prediction for nitrile homopolymer Tg's are compared with literature values.
