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. ^ 18 cl, 3 tbl |
