  • Patent number: 8058355
    Abstract: The present invention provides solvent- and water-based primer compositions that include at least one chlorinated carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The chlorinated carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof then chlorinated. The chlorinated carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified chlorinated carboxylated polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified chlorinated carboxylated polyolefins water-dispersible.

  • Publication number: 20110086980
    Abstract: An adhesive composition for use in bonding of a polarizing plate is prepared from acrylic-based polymer graft-polymerized and modified by a reactive silane coupling agent with a specific grafting position and an ordinary cross-linking agent. Compared with unmodified acrylic-based copolymers, the adhesive composition thus synthesized demonstrates high adhesion property, cohesion property, elasticity property and high durability and, when used in bonding of the polarizing plate, flexibly follows dimensional changes of the polarizing plate in a high-temperature high-humidity atmosphere, alleviates the phenomenon where the polarizing plate demonstrates uneven distribution of residual stress due to dimensional changes of the polarizing plate, and prevents light leakage and uneven color which might otherwise occur to the polarizing plate due to the aging, cracking, or peeling of a conventional adhesive.

  • Patent number: 7897654
    Abstract: In one aspect, the invention relates to silicone prepolymer compositions comprising a silicone prepolymer and a solvent. A soluble silicone prepolymer can be provided having increased average silicon content, thereby attaining a desired oxygen permeability. A solvent can be provided with a desired balance between hydrophilicity and hydrophobicity by selection and modification of the solvent molecular structure, resulting in molded polymer films and articles that exhibit minimal or nonexistent eye irritation and exhibit highly transparent products. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

  • Publication number: 20090224421
    Abstract: The invention relates to a rotomolding process for forming a multi-layer article of two different polymers with different melting points in which an outer layer polymer powder is added to a rotational molder along with an inner layer polymer powder that is separated from the outer layer powder by a release film. The release film has a particular melting point that is greater than that of the outer layer polymer and preferably between the melting points of the inside layer and outside layer polymers. In one embodiment, the release layer forms an enclosure or bag in which the inner layer (higher melting point) powder is enclosed. In another embodiment the release film forms a barrier between an insulated cavity and the mold. The process provides a means for a “one-shot” rotomolding method.
