UV-SOLIDIFIED ORGANOSILICON COMPOSITION FOR FIBRE LIGHT GUIDE COVERING Russian patent published in 1998 - IPC

FIELD: technology of fibre light guide making, organic chemistry. SUBSTANCE: composition has prepolymer of the following general formula: where a = 0.98-1.00; b = 0-0.03; n > 10 and R is -(CH₂)_mOCONHR¹ or -(CH₂)_mNHCONHR¹ where m - whole number from 1 to 20; R¹ is where R² is -O(CH₂)₂OCOCR³=CH₂ or -OCH(CH₃)CH₂OCOOCR³=CH₂ and R³ is H or CH₃ at the following ratio of components: prepolymer 97-99.5 wt.-%, photoinitiating agent 0.5-3 wt.-%, and inhibitor 10-500 ppm. Composition is used for making light guide covered by shell made of organosilicon UV-solidified polymers. EFFECT: improved method of synthesis, improved quality of polymers. 1 tbl, 5 ex
