POLYDIORGANOSILOXANES AND COPOLYDIORGANOSILOXANES AS FILM-FORMING MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2083602 C1

FIELD: polymers. SUBSTANCE: product: polydiorganosiloxanes of the general formula [(R′)(C6H5)SiO]l[(C6H5)2SiO]m where: R′ - C2H5, n-C4H9, n-C6H13;; l = 16.7-33.3; m = 66.7-83.3, and copolydiorganosiloxanes of the general formula where: R′ - n-C6H13; R″ - CH2=CH; l = 2.8-16.7; m = 66.7; n = 16.6-30.5, or R′=R″ - n-C6H13, n-C4H9; l = 1.1-6.7; m = 66.7; n = 26.6-32.2. Proposed substances were used for producing the film-forming materials exhibiting mesomorphic properties. EFFECT: enhanced quality of materials. 2 cl, 2 tbl
