Abstract: Provided is a curable silicone composition for a release agent which can form a release film having a silicone adhesive with a low release force even when thin and which does not reduce the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. A release film and laminate are also provided. The curable silicone composition comprises: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing the following components (A1) and (A2) at a mass ratio of 1/99 to 45/55: (A1) a fluoro(poly)ether modified organopolysiloxane having at least two alkenyl groups per molecule along with a fluoro(poly)ether-containing organic group; (A2) a fluoroalkyl group-containing organopolysiloxane having at least two alkenyl groups per molecule along with a fluoroalkyl group having 1 to 12 carbon atoms; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation reaction catalyst; and (D) an organic solvent.

Abstract: A thermoplastic composition includes: a first branched polycarbonate copolymer end-capped with 4-hydroxybenzonitrile (4-HBN) having a molecular weight M1; and a second branched polycarbonate copolymer end-capped with 4-HBN having a molecular weight M2. M1 is less than M2. Methods for determining entanglement molecular weight (Me) of a polycarbonate copolymer include: preparing a sample of a branched polycarbonate copolymer including a 1,1,1-tris-hydroxy-phenylethane (THPE) branching agent and that is end-capped with 4-HBN; determining phase angle (∂) versus complex modulus (G*) of the sample using a small amplitude oscillatory rheology process at a specified temperature; determining a minima in the ∂ of the sample; determining a plateau modulus (GN) of the sample from the determined minima of ∂; and calculating the Me of the sample from the GN.

Abstract: The present invention provides: a highly transparent optical member which is formed from a silicone resin or a silicone rubber, and which has less mass change and excellent heat resistance without causing contact faults, or deterioration or contamination of the surface of other members due to adhesion to an electronic circuit or the surfaces of other members; and a production method for producing said optical member. According to the production method, the content of low-molecular-weight siloxanes D3-D20 in a optical member is reduced to an infinitesimal amount with use of a plurality of different low-molecular-weight siloxane removal steps.

Abstract: Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
