Abstract

Long‐chain polyamides (polyethyleneamides) were prepared from polyethylenes bearing in‐chain carbonyl groups (polyethyleneketones) by the oxime formation and successive Beckmann rearrangement. (Diethylamino)sulfur trifluoride (DAST) was utilized as a promoter, which allowed mild conversion of the oxime group in spite of low solubility of the polymers. The polyethyleneamide exhibited different tensile property compared to a commercial HDPE. [ABSTRACT FROM AUTHOR]
