Abstract:

R,R)/(S,S)-cyclohexene-1,2-diols were used as starting materials to synthesize various isotactic and syndiotactic model compounds(oligomers with 2—12 degrees of polymerization) of poly(cyclohexene carbonate)(PCHC) through an iterative coupling method using two orthogonal protecting groups and acrylation reagents. These stereoregular oligomers were characterized by high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy. The stereoregularity of PCHC can be accurately calculated by comparing the integral area of each peak in the carbonyl carbon regions of the 13C nuclear magnetic resonance spectrum.

Key words: Discrete, Oligomer, Poly(cyclohexene carbonate), Isotactic, Syndiotactic
