摘要 |
A process for preparing a bound antioxidant polymer concentrate is described which comprises grafting one or more acrylic or alkylacrylic esters or amides containing a hindered-amine group onto the polymer in the presence of a radical generator at a temperature of 100 DEG to 350 DEG C, the molar ratio of said radical generator to said ester or amide being from 0.001: to 1:1, the reaction being continued for a time such that the melt viscosity of the polymer which increases initially during the reaction has reduced to a level which permits the concentrate to be homogeneously blended subsequently into a unstabilised polymer. |
