FIELD: chemistry. ^ SUBSTANCE: disclosed is a composition for polycondensation polymerisation of a polycondensed polymer, containing a polycondensed polymer selected from polyester and polyamide and at least one metal-based compound selected from a group consisting of R7Si7O12Al, R7Si7O12TiOH, (R7Si7O12)2Zn4Me2, R7Si7O12Zr(O-i-C3H7) and R7Si7O12Ge(O-i-C3H7), where R is selected from a group consisting of (i-C4H9) and phenyl. Disclosed also is a method for polycondensation of a polymer selected from polyester and polyamide using the disclosed composition. ^ EFFECT: polymer obtained using the disclosed method does not yellow and does not decompose under polymerisation process conditions. ^ 25 cl, 2 tbl |
