CATALYTIC SYNTHESIS OF MC NYLON WITH SODIUM METHYLATE

The technological process of catalytic synthesis of MC Nylon with sodium methylate instead of the conventionallyused catalyst-grain sodium hydroxide is researched. The feeding pattern of the catalyst is improved. The method i. e. using sodium methylate solution to replace grain sodium hydroxide, is beneficial to the accurate calculation of catalyst. The experimental results show that the technology of the catalytic synthesis of MC Nylon with sodium methylate is simple, the productivity can be raised, the formation of gas hole can be reduced and the product color is lighter, the mechanical property keeps constant and the unpolymerized phenomenon that is caused by the fluetuation of reaction condition is avoided.
