Patent ID: 7807757

Claim:
A process for stabilising and at the same time phase compatibilising plastics or plastic compositions comprising at least two different polymers by incorporating polymeric compounds obtained by reacting a benzotriazol, of formula (VI) R 18 is —(CH 2 ) t —R 20 or R 19 is C 1 -C 12 alkyl, α,α-dimethylbenzyl or a radical R 20 is —OH, —SH, —NHR 30 , —SO 3 H, —COOR 21 , —CH═CH 2 , —(CO)—NH—(CH 2 ) u —NCO; R 21 is hydrogen, or —CH 2 —CH(OH)—CH 2 —O—(CO)—R 22 ; R 22 is C 1 -C 4 alkyl or phenyl; R 30 is hydrogen or C 1 -C 9 alkyl; is 0 or 1; t is a number from 0 to 6; u is a number from 2 to 12; with a compatibiliser to form the polymeric compound, wherein the compatibiliser compound is a polymer with acrylic acid, glycidyl methacrylate, methacrylic acid, maleic anhydride or vinyl alcohol and the formed polymeric compound has unreacted acid, glycidyl, anhydride or alcohol functionality.
