Abstract
1429585 Lactam polymerization catalysts BAYER AG 16 May 1974 [18 May 1973] 21741/74 Heading C3R Polyamides are made by polymerizing #1 lactam having #5 ring-members in the presence of an activator and a catalyst being an alkali or alkaline-earth metal salt of #1 polyalkylene glycol. The polyalkylene glycol salts are made by reacting the glycol with an alkali or alkalineearth metal or its alcoholate, amide, hydride, or Grignard compound.
