Abstract:
In this paper the synthetic method for MC nylon modified with laurolactam is presented. The copolymer of caprolactam with laurolactam can be prepared by activated anionic copolymerization under the adiabatic condition. The dynamic modulous Gc and mechanical damping tan D of the copolymer can bemeasured by means of the free vibration on a torsion pendulum. It is evident that the A-max imum temperature TA varies with the concentration of comonomers. A remarkable decrease in TA is shown with the ratio of 10 mole laurolactam to 90 mole caprolactam in the copolymer. The effect of modifiedMC nylon on its properties has been investigated, with the dependence of the properties on the amount of laurolactam examined. It is obvious that the notched impact strength and deformability will be increased with the increase in laurolactam content of the copolymer.
