METHOD FOR TRAPPING A RESIDUAL MONOMER WITH EPOXIDE FUNCTIONIN A THERMOPLASTIC COMPOSITION |
摘要 |
The invention concerns a method for trapping a residual monomer which has no t reacted by polymerisation of by grafting comprising at least an epoxide function in a thermoplastic composition based on an ethylene and/or propylene copolymer and at least a monomer including at least an epoxide function. Said method comprises the following steps: preparing said thermoplastic composition; adding in sufficient amount of an additive for Lewis or Brönste d acid trapping of said residual monomer. The trapping additive is preferably a porous zeolite whereof the pore diameter ranges between 2 and 10 angstroms. The invention also concerns the composition obtained by said method and mixtures comprising said composition.
