Summary

The method of modification of PA 6 by paraffin oil during the bulk anionic polymerization of caprolactam has been developed. The preparation of uniform casts, containing up to 11 wt. % of oil, is possible due to the method. The influence of modifier content on the structure of mo­dified polymer and its mechanical properties has been determined. it has been found that the decrease of spherullte size without any change in the polymer crystallinity decree is produced by the modification. The hardness, flexural modulus and compressive strength at yield are decreased, while the impact strength of PA 6 is increased.
