Abstract

1426791 Modified diene polymers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 3 April 1973 [5 April 1972] 15896/73 Heading C3P Conjugated diene homo- and co-polymers are modified by (A) forming a mixture of solid polymer with 0À01-5 wt. per cent of an aromatic sulphonyl azide containing one or more carboxyl groups attached to the aromatic nucleus and having a melting point below 140‹ C., the temperature at which said mixture is formed being between 40‹ C. and 140‹ C., and (B) heating the resulting mixture for at least 30 seconds and at most 10 minutes at a temperature between 140‹ C. and 250‹ C. such that the polymer remains in the solid state. Step (A) may be conducted by blending solid polymer with molten azide or by adding azide to a solution of the polymer and removing the solvent at between 40‹ C. and 140‹ C. A reinforcing filler and other conventional rubber additives may be present during the treatment. Examples are directed to the modification of cis-1,4-polyisoprene with one of the following azides: 3 - azidosulphonyl - benzoic acid, 2- hydroxy - 5 - azidosulphonyl - benzoic acid, 2 - chloro - 5 - azidosulphonyl - benzoic acid, 4 - azidosulphonyl - 1,2 - benzene dicarboxylic acid, 4 - ethyl - 5 - azidosulphonylbenzoic acid and 2 - methoxy - 5 - azidosulphonylbenzoic acid.
