METHOD OF SYNTHESIS OF POLYCAPROAMIDE Russian patent published in 2002 - IPC

Abstract RU 2187517 C2

FIELD: chemistry and technology of polymers. SUBSTANCE: invention relates to synthesis of polycaproamide. Method involves polymerization of ε-caprolactam in the presence of amine thermostabilizing agent. Octafluoropentanol of the formula HCF2(CF2)3CH2OH in the amount 0.00085-0.001% is added to the polymerization system additionally. Method ensures to obtain polycaproamide with enhanced thermostability and decrease the consumption of amine thermostabilizing agent. EFFECT: improved method of synthesis. 1 tbl, 6 ex
