    摘要: For trapping a residual monomer containing an expoxide function that has not reacted by copolymerization or by grafting, in a thermoplastic composition based on a copolymer of ethylene and/or propylene, a sufficient amount of an acidic trapping additive is added to remove the residual monomer. The trapping additive is preferably a porous zeolite with a pore diameter of between 2 and 10 angstroms. Improved compositions and blends are thereby obtained.
