| titleOfInvention | Method for preparing poly (gamma-butyrolactone) by efficiently catalyzing ring opening of gamma-butyrolactone |
| abstract | A method for preparing poly (gamma-butyrolactone) by efficiently catalyzing ring opening of gamma-butyrolactone, which comprises the following steps: the gamma-butyrolactone and the catalytic system are subjected to ring-opening polymerization reaction to obtain linear or cyclic poly-gamma-butyrolactone with different molecular weights and molecular weight distributions. The catalytic system comprises strong base, initiator and hydrogen donor electron, wherein the strong base is tetrabutyl ammonium hydroxide, and the initiator comprises various alcohols. The method has the advantages of high-efficiency controllable polymerization, low cost, capability of carrying out polymerization under mild conditions and wide molecular weight distribution. The hydrogen donor electron structure used therein is as follows: the R group is an aliphatic group or an aryl group; the X group is O or S. |
