Patent ID: 6849697

Claim:
A process for preparing a polyphenylene sulphide composition consisting essentially of 60 to 99.5% by weight of polyphenylene sulphide and 0.5 to 40% by weight of a combination (C) containing a compound (C1) chosen from olefinic elastomers containing epoxy groups and a compound (C2) chosen from crosslinking agents containing functional groups which are reactive towards the epoxy groups of the compound (C1) and selected from the group consisting of amino, hydroxyl, carboxyl and carboxylic acid anhydride groups, wherein the process comprises melt-blending a mix containing the polyphenylene sulphide and the compounds (C1) and (C2) of the combination (C), wherein this blending is performed by incorporating each of the compounds (C1) and (C2) of the combination (C), successively and in any order, into the polyphenylene sulphide.
