PROCESS FOR PREPARING AN N-ALKYLLACTAM WITH IMPROVED COLOR QUALITY

摘要

The present invention relates to a process for purifying an N-alkyllactam which comprises contacting N-alkyllactams with carbon. The present invention also relates to mixtures comprising poly(vinylidene fluodride) (PVDF) and N-alkyllactams, in which the N-alkyllactams have been purified by contacting the N-alkyllactam as well as a method for their production. The present invention also relates to the use of said mixtures in processing PVDF for applications in which improved color is a quality requirement.
