METHOD OF MODIFYING POLYDIMETHYLSILOXANE RUBBER Russian patent published in 2003 - IPC

FIELD: rubber industry. SUBSTANCE: polydimethylsiloxane rubber is modified by UV irradiation in presence of photoinitiator and reagent forming active groups, said photoinitiator being organic carbonyl-containing compounds selected from aromatic ketone and quinone series, taken in amounts 0.001-0.01 mole/1 kg rubber, at 50-150 C for 30-90 min in atmosphere of air oxygen as above- mentioned reagent. Thus formed active groups are further substituted by reaction with oxygen- or nitrogen-containing substituting reagents such as amines, amino acids, hydrazines, alcohols, and orthoethers. EFFECT: enabled production of rubber with specified structure. 1 tbl, 2 ex
