TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polysiloxane includes siloxane moieties of formulae ((ORI)aO(3-a)/2Si-AR-SiO(3-b)/2(ORII)b) (2a), (R1R2SiO(2-c)/2(ORIII)c) (2b) and at least one siloxane moieties of formulae (R3SiO(3-d)/2(ORIV)d) (2c), (R4R5SiO(2-e)/2(ORV)e) (2d) and (R6R7R8SiO1/2) (2e). The polysiloxane has a structure of formula ((R6R7R8SiO1/2)m((ORI)aO(3-a)/2Si-AR-SiO(3-b)/2(ORII)b)n(R3SiO(3-d)/2(ORIV)d)p(R1R2SiO(2-c)/2(ORIII)c)q(R4R5SiO(2-e)/2(ORV)e)r) (3a). The polysiloxane is included in 500 wt.% or more, preferably 50-99.9 wt.%.RI-RV = H or 1-10C alkyl (optionally substituted);R1-R8 = 1-10C alkyl, 3-20C cycloalkyl, l-10C hydroxyalkyl, 6-20C aryl, 2-20C heteroaryl, 2-10C alkenyl, l-10C alkoxy, carboxyl or glycidylether (all optionally substituted), lactone and/or hydroxyl;a, b, d = 0-2;c, e = 0-1;m, p, q, r = greater than 0 and less than 0.9; andn = greater than 0 and less than 0.2, where m+n+p+q+r is 1. EXAMPLE - Phenylmethyldimethoxysilane (1822.5 g) and 1,4-bis(triethoxysilyl)benzene (0.84 g) were added at 25 degrees C. Tetramethylammonium hydroxide (0.46 g) was added over 10 minutes with stirring at 25 degrees C. The mixture was then heated to 50 degrees C and water (180 g) was added over 120 minutes. The mixture was heated at 65 degrees C for 5 hours and then cooled to room temperature. The resulting mixture was neutralized with acetic acid and washed with water. The resulting polymer was dried under vacuum and then 1,3-divinyltetramethyldisiloxane (372.8 g) and sulfuric acid (95-98%, 10 g) were added and the mixture was stirred for 12 hours at room temperature. The mixture was then washed with water and volatiles removed under reduced pressure to a polysiloxane polymer of formula ((SiO3/2-C6H4-SiO3/2)(0.002)(CH3-C6H4SiO2/2)(0.955)(vinyl(CH3)2SiO1/2)(0.043)) (A). The polysiloxane (A) (90 parts by weight (pbw)) and vinyl-capped polyphenylsilsequioxane (vinyl group amount: 1mmol/g, 10 pbw) were mixed and added with hydrogen capped polyphenylmethylsiloxane (hydrogen amount: 5 mmol/g) to maintain the ratio of hydrogen and vinyl group (H/Vi) at 1. Then it was defoamed under vacuum to provide a liquid resin composition.
