METAL AND POSS BASED COMPOUNDS FOR PRODUCING POLYCONDENSED POLYMERS Russian patent published in 2012 - IPC C08G63/85 C08G69/28

Abstract RU 2450030 C2

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 R₇S_i7O₁₂Al, R₇S_i7O₁₂TiOH, (R₇S_i7O₁₂)₂Zn₄Me₂, R₇S_i7O₁₂Zr(O-i-C₃H₇) and R₇S_i7O₁₂Ge(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.
