Abstract: Described herein are compositions comprising a vinyl acrylic copolymer derived in the presence of maltodextrin. In some examples, the compositions comprise a copolymer derived from: vinyl acetate; an acrylate monomer having a Tg of ?30° C. or less; a carboxylic acid, a carboxylic acid anhydride, or a combination thereof; and an organosilane; in the presence of maltodextrin. The copolymer can be provided as an aqueous dispersion. In some examples, the aqueous dispersion can have an overall solids content of from 40% to 75%. Also disclosed herein are carpet tiles having a surface coated with the adhesive formulations disclosed herein. In some examples, the carpet tile with the adhesive formulation applied thereto can pass the British spill test. Also disclosed herein are methods of making the compositions disclosed herein.

Abstract: A double side polishing apparatus comprises an upper polishing plate and a lower polishing plate for polishing both sides of a wafer; a plurality of carriers, each including a center plate and a circumferential plate, the center plate having a mounting hole where the wafer is mounted, the circumferential plate having a fitting hole where the center plate is fitted and a gear part formed along the outer periphery thereof, the center of the mounting hole being eccentric from the center of the center plate, the center of the fitting hole being eccentric from the center of the circumferential plate; and a sun gear and an internal gear engaged with the gear part to transmit a rotational force to the plurality of carriers, wherein a fitting direction of a center plate into a fitting hole is adjustable for at least two carriers among the plurality of carriers.

Abstract: Provided are an apparatus and a method for sawing a single crystal ingot. The apparatus includes a wire saw sawing an ingot, a roller driving the wire saw, and a bath containing a liquid cooling the ingot before sawing the ingot.

Abstract: A benzothiadiazol-cyclopentadithiophene copolymer comprising as repeating unit the group of the formula (I) wherein R is n-hexadecyl or 3,7-dimethyloctyl, and having a number average molecular weight Mn in the range of from 30 to 70 kg/mol is disclosed. The invention also relates to the use of the copolymers as semiconductors or charge transport materials, as thin-film transistors (TFTs), or in semiconductor components for organic light-emitting diodes (OLEDs), for photovoltaic components or in sensors, as an electrode material in batteries, as optical waveguides or for electrophotography applications.
