摘要：

The bulk polymerization of 2,3-dihydro-4H-pyran catalyzed by 12-tungstophosphoric acid was investigated. The effects of the time, temperature, and amount of the catalyst on the polymerization reaction were studied. The propagation exclusively involved C=C bonds. Propagation by ring opening was not observed. The total polymerization time and the melting temperature decreased as the proportion of the catalyst and the temperature were increased because of the increase in the number of active centers and the chain-transfer reaction, respectively.
