Nylon‐6 is synthesised from ε‐caprolactam by an anionic polymerisation method, through a two‐step process using sodium metal as a catalyst and diisocyanate‐caprolactam block initiator. Two different aliphatic diisocyanates are used. The effects of diisocyanate structure and concentration on percentage cryslallinity, molecular weight, density and thermal properties of nylon are discussed.
