| MC nylon, is called monomer casting nylon. MC nylon has lots of very good properties, such as light quality, no noise and good mechanical properties, and so on. But comparing to metal, owing to MC its low strength, modulus and heat distortion temperature, bad size stabilization, and high notch sensitivity, the usefulness of MC nylon is still limited. So we have to improve its integrated properties.The anionic ring-opening polymerization of ε -caprolactam is an important method for synthesis of nylon 6 and its copolymers. It is well known that the changing of synthesize conditions has a substantial effect on the degree of conversion, the molecular weight , molecular weight distribution, degree of crystallinity, morphology, and mechanical properties behavior. The amount of catalysts, containing initiators and activators, is one of the most important factors controlling the rate of polymerization. The initiators control the polymerization rate, and the activator control the molecular weight.Rigid inorganic particles in situ polymerization so simple that is good for deep study, but must to solve the dispersibility in the matrix.we synthesized four series MC nylon by anionic polymerization of CL using... |
