INHERENTLY PHOTO- AND THERMOSTABILIZED POLYAMIDE, METHOD OF ITS SYNTHESIS, THREADS OBTAINED BY HIGH-SPEED FORMING AND FABRICS OBTAINED FROM THREADS Russian patent published in 2001 - IPC

FIELD: polymers. SUBSTANCE: invention describes method of synthesis of polyamides by polymerization or polycondensation of monomers where caprolactam or adipic acid and hexamethylenediamine or their salt are used. Process of polymerization or polycondensation of monomers is carried out in the presence of triacetonediamine of the formula (I) used in the amount at least 0.03 mol.% as measured for mole of carboxamide groups in synthesized polyamide. Polyamides synthesized by this method are photo- and thermostabilized ones and used for making threads by method of high-speed forming and fabrics also. EFFECT: improved method of synthesis and producing. 7 cl, 7 tbl
