| Abstract: | The block copolymerization of caprolactam by anionic initiator with polymeric activators is studied. The soft segment, polybutadiene or polyether prepolymers used as activators are introduced on the polyamide chain through copolymerization for improving the low temperature impact strength and tenacity of cast nylon products. The effects of the prepolymer length and weight ratio on the properties of block copolymers are investigated. Significant results are obtained. |
