NOVELTY - An organopolysiloxane comprises siloxane unit (A) (I) and siloxane unit (B) (II). The siloxane unit (B) comprises siloxane unit (B-1) and siloxane unit (B-2). The ratio of siloxane unit (A) with respect to the sum of siloxane unit (A) and the siloxane unit (B) is 30-60 mol%. The ratio of sum of siloxane unit (A) and siloxane unit (B) with respect to all the siloxane units is 90-100 mol%. The mole ratio of product of 100 and siloxane unit (B-1) with respect to sum of content of siloxane unit (B-1) and siloxane unit (B-2) is 25-90.    USE - Organopolysiloxane is used for crosslinked material, coating composition (all claimed) and manufacture of glass laminated material. Uses include but are not limited to solar cell, liquid crystal panel, organic electroluminescent panel, plasma display panel, field emission panel, mobile phone, secondary battery, passive drive-type display apparatus, active drive-type display apparatus, thin film transistor, etc.    ADVANTAGE - The organopolysiloxane has excellent adhesiveness with respect to glass substrate material. Decomposition of organopolysiloxane at high temperature is suppressed.    DETAILED DESCRIPTION - An organopolysiloxane comprises siloxane unit (A) of formula (I) and siloxane unit (B) of formula (II). The siloxane unit (B) comprises siloxane unit (B-1) and siloxane unit (B-2). The ratio of siloxane unit (A) with respect to the sum of siloxane unit (A) and the siloxane unit (B) is 30-60 mol%. The ratio of sum of siloxane unit (A) and siloxane unit (B) with respect to all the siloxane units is 90-100 mol%. The mole ratio of product of 100 and siloxane unit (B-1) with respect to sum of content of siloxane unit (B-1) and siloxane unit (B-2) is 25-90.    R1-R4=4C or less alkyl;    Ar'=optionally substituted phenylene;and    R5,R6=3C or less alkenyl or 4C or less alkyl.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of organopolysiloxane, which involves dripping 70-40 mol% silane compound of formula (IV) into 30-60 mol% silane compound of formula (III) and reacting, or reacting by adding simultaneously silane compound (III) and silane compound (IV) into a solvent; and    (2) crosslinked material, which is obtained by crosslinking the organopolysiloxane.    X,Y=H, hydrolyzable group or hydroxy.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the glass laminated material.
