Polymerization by phase transfer catalysis

Summary Polycarbonates, polythiocarbonates, and polyesters from 1,1,3-trimethyl-3-(4-hydroxy-phenyl)-4-indanol were synthesized using phase transfer conditions. THe effects of several catalysts and reactions times were evaluated by the yields and inherent viscosities. Phase transfer catalysis was not an efficient technique due to the rigid structure of the diphenol with the indanic group. The results were compared with that obtained with a diphenol having the same number of carbon atoms but forming an aliphatic side chain.For part 12, see ref. 7
