Abstract: The present invention provides a starch-(meth)acrylate graft copolymer and the preparation process thereof. The starch-(meth)acrylate graft copolymer is prepared by copolymerizing (meth)acrylate monomer and starch in a weight ratio of (0.4˜8):1, the graft copolymer having a skeleton of large starch molecule is grafted with one or more (meth)acrylate monomer with a grafting ratio of no less than 70%. The present invention further provides an oil swellable material, which comprises the starch-(meth)acrylate graft copolymer above as the swelling agent; and also an oil- and water-swellable material, which comprises the starch-(meth)acrylate graft copolymer above, water absorbing agent, reactive monomer, surfactant and material matrix. Further, sealing articles and packers prepared from the above oil swellable material and oil- and water-swellable material are also provided.

Abstract: The present invention is directed to a pneumatic tire having a wire-reinforced component comprising (A) a metallic wire; and (B) a rubber composition contacting the wire, the rubber composition comprising (1) a diene based elastomer; and (2) from 2 to 20 phr of at least one carboxylic acid selected from the group consisting of salicylic acid and dithiodipropionic acid.

Abstract: A rubber latex composition is disclosed having reduced allergenicity. Methods for producing a rubber latex composition having reduced allergenicity are also disclosed.

Abstract: Disclosed are a synthetic resin composition for use as building materials such as window frames, as well as a product manufactured using the same. More particularly, the synthetic resin composition comprises a tetrapolymer of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyanide monomer and a styrene-vinyl cyanide copolymer having a high molecular weight and a high degree of dispersion. Unlike products manufactured using prior polyvinyl chloride (PVC), building material such as window frames manufactured using the synthetic resin composition are recyclable, and thus can contribute to a reduction in the generation of hormone-disrupting chemical dioxin, which is released in the burning thereof. Also, the resin composition can be manufactured into products having excellent properties of weather resistance and colorability without using environmental pollutants such as cadmium stearate or lead stearate, which are used as thermal stabilizers.

Abstract: Multistage polymers predominantly stabilized by nonionic emulsifiers and derived from hard and soft monomer compositions containing vinyl esters, of which at least one monomer composition must contain an unsaturated compromisable organosilicon compound, are described. The plastic dispersions can be used as binders in emulsion paints and finishes and impart to these excellent scrub resistance in addition to good blocking resistance.

Abstract: Elastomeric compositions comprising at least one C4 to C7 monoolefin elastomer, at least one polyalphaolefin, and optionally at least one hydrocarbon polymer additive are disclosed. The PAO comprises oligomers of one or more C2 to C20 alpha-olefins having a kinematic viscosity at 100° C. of 3 to 3000 cSt and a Mw/Mn of less than 4. In one aspect, the elastomeric composition may have improved flex fatigue properties and have a fatigue life of 450,000 Kc or more as measured by ASTM D 412 die C. In another aspect, an elastomeric composition may have improved impermeability and have a permeation coefficient at 40° C. of 160 cc*mm/(m2?day) or less.

Abstract: The present invention provides a taste-masked composition containing an active compound. The composition is taste-masked by employing a loaded polymeric matrix which is produced by incorporating or complexing the active compound on a polymeric matrix having ionic functional groups and removing unbound active compounds from the polymeric matrix.
