    摘要： A cross-linked composition comprises the reaction product of a first reactant having at least one hydroxyl or amine (functional) group, a second reactant having at least one hydroxyl or amine (functional) group, and a siloxane having at least two terminal anhydride groups reactive with the functional groups of the first and second reactants. The first reactant is selected from the group of first siloxanes having at least one hydroxyl or amine group, a first organic alcohol having at least one hydroxyl group, a first organic amine having at least one amine group, or combinations thereof. The second reactant is selected from the group of second siloxanes having at least one hydroxyl or amine group, a second organic alcohol having at least one hydroxyl group, a second organic amine having at least one amine group, or combinations thereof. If utilized, the first siloxanes and/or second siloxanes are different from the siloxane.

    摘要： Organosiloxane block copolymers, curable compositions, and solid compositions derived from these block copolymers are disclosed. The organosiloxane block copolymers comprise: 40 to 90 mole percent disiloxy units of the formula [R12—SiO2/2] 10 to 60 mole percent trisiloxy units of the formula [R2SiO3/2] 0.5 to 35 mole percent silanol groups [≡SiOH] where R1 is independently a C1 to C30 hydrocarbyl, R2 is independently a C1 to C20 hydrocarbyl, wherein; the disiloxy units [R12SiO2/2] are arranged in linear blocks having an average of from 10 to 400 disiloxy units [R12SiO2/2] per linear block, the trisiloxy units [R2SiO3/2] are arranged in non-linear blocks having a molecular weight of at least 500 g/mol, and at least 30% of the non-linear blocks are crosslinked with each other, each linear block is linked to at least one non-linear block, and the organosiloxane block copolymer has a molecular weight (Mw) of at least 20,000 g/mole.
