Poly1,4-cyclohexanedimethyl-1,4-cyclohexanedicarboxylatePCCD was prepared by melt polycondensation of 1,4-cyclohexanedimethanol CHDM and 1,4-cyclohexanedicarboxylic acid CHDA . The paper investigated the effect of esterification temperature and stirring rate on reaction degree and gained the optimal preparing conditions. FTIR and NMR were used to analyze the product and the result demonstrated the structure of PCCD. The optical tests show that PCCD is a kind of transparent polymer having high transmittance, low haze and yellow index, and low stress-optical coefficient.
