CATALYSTS FOR POLYESTER PRODUCTION |
| 摘要 |
Novel catalysts for polyester production by esterification and/or transesterification are MoS2 or WS2 which have been intercalated by alkali metals cations, especially lithium cations, and then contacted with an alcohol or a polyol, a preferred polyol being a glycol which is one of the monomeric units in the polyester produced.
