POLYCARBONATE MOULDING COMPOUNDS Russian patent published in 2011 - IPC C08L69/00 

Abstract RU 2431649 C2

FIELD: chemistry.

SUBSTANCE: composition contains a mixture of a first graft polymer B and a second graft polymer C and, if necessary, (co)polymers, wherein the average molecular weight of the free (co)polymer in the graft polymer B is at least 32000 g/mol lower than the average molecular weight of the mixture of free (co)polymer C in the graft polymer C and (co)polymer D.

EFFECT: composition is characterised by good hydrolysis resistance and processing stability.
