Homogeneous polymerization of propargyl alcohol (OHP) with Pd (CCCH 2 OH) 2 (PPh 3 ) 2 [PdC] catalyst in CHCl 3 ‐CH 3 OH mixed solvent system has been investigated. [PdC] was found to be a novel effective catalyst for the OHP polymerization. Some features, kinetic behavior, and effect of solvent for the OHP polymerization are described and discussed. The overall polymerization activation energy was found to be 75.6kJ/mol and the rate equation can be expressed as R p = k p [OHP] [PdC] 0.7 , where k p = 3.14 × 10 ‐4 L 0.7 / mol 0.7 S (60°C). Polypropargyl alcohol (POHP) obtained is a brown powder with a number‐average molecular weight ( M̄ n ) of 10 3 ‐2 × 10 3 , and soluble in MeOH, DMF, and DMSO. Conducting properties of the resulting POHP were investigated.
