| 摘要 |
The invention relates to a method for purifying a polyester including impurities, said impurities including at least 0.1 % by weight of a polyester or of residual monomer(s), including at least one step of: (ii) adding, to the polyester in a solvent, a functionalized material selected between a PAMAM dendrimer and a resin functionalized by one or more primary and/or secondary amine functions. Said method enables a low level of residual monomer(s) to be obtained while providing economically and environmentally advantageous reaction conditions. |
