  • Patent number: 6720390
    Abstract: Disclosed is a process for crosslinking copolymers of acrylic esters by converting some of the ester groups to ester or amide groups which contain unsaturation, and then sulfur or peroxide curing the resulting polymers. The resulting crosslinked polymers often have excellent vulcanizate properties, and are useful especially in elastomeric form as seals and gasket.

  • Patent number: 6716949
    Abstract: The invention is directed to amphipathic polymeric particles that serve as both the dispersant and the binder in water based inks, ink compositions containing these particles, and methods for making the particles. The polymeric particles contain both hydrophilic and hydrophobic moieties with a pre-determined structure, and have an average diameter of 50 to 500 nm. The amphipathic polymeric particles may be prepared by a side-chain conversion method or a polymerization process involving an ATRP step, with or without a cross-linking agent. This invention improves the stability of polymer and inks by both ionic and steric stabilization of the suspended polymer particles.

  • Publication number: 20030100695
    Abstract: Disclosed is an organic anti-reflective film composition suitable for use in submicrolithography, comprising a compound of Formula 13 and a compound of Formula 14 . The organic anti-reflective film effectively absorbs the light penetrating through the photoresist film coated on top of the anti-reflective film, thereby greatly reducing the standing wave effect. Use of organic anti-reflective films of the present invention allows patterns to be formed in a well-defined, ultrafine configuration, providing a great contribution to the high integration of semiconductor devices.

  • Publication number: 20020160301
    Abstract: The present invention provides a cross-linker monomer of formula 1, a photoresist polymer derived from a monomer comprising the same, and a photoresist composition comprising the photoresist polymer. The cross-linking unit of the photoresist polymer can be hydrolyzed (or degraded or broken) by an acid generated from a photoacid generator on the exposed region. It is believed that this acid degradation of the cross-linking unit increases the contrast ratio between the exposed region and the unexposed region. The photoresist composition of the present invention has improved pattern profile, enhanced adhesiveness, excellent resolution, sensitivity, durability and reproducibility.

  • Patent number: 6455655
    Abstract: This invention discloses an emulsion styrene-butadiene rubber (SBR) that can be employed in manufacturing tire tread formulations that have rolling resistance and treadwear characteristics that are similar to those made with solution SBR but with improved traction characteristics. Thus, the emulsion SBR of this invention is superior in many respects for use in tire tread compounds to conventional solution SBR and conventional emulsion SBR. This invention more specifically discloses a styrene-butadiene rubber composition which is comprised of repeat units which are derived from styrene, 1,3-butadiene, and a hydroxy alkyl acrylate monomer, wherein the styrene-butadiene rubber composition has a number average molecular weight as determined by field flow fractionation which is within the range of about 50,000 to 150,000, and wherein the styrene-butadiene rubber has a light scattering to refractive index ratio which is within the range of 1.8 to 3.9.

  • Patent number: 6423806
    Abstract: A heat resistant resin is formed by heating an acrylic monomer composition prepared by copolymerising an acrylic monomer represented by general formula (1) with another monomer that is copolymerisable with the acrylic monomer, the acrylic monomer composition having an acid value of 5 mgKOH/g or less, where each of R1 and R2 is either a hydrogen atom or an organic residue. A 1% tetrahydrofuran solution formed by subjecting the acrylic copolymer to a heat treatment at a temperature of 250° C. for 30 minutes and thereafter dissolving the acrylic copolymer in tetrahydrofuran has a viscosity ranging from 10 cps to 10,000 cps at 25° C. The acrylic polymer does not gel in the manufacture of a heat resistant resin, and by using the acrylic polymer as a material for a heat resistant resin, the resultant heat resistant resin obtained boasts excellent transparency and mouldability, and can be moulded by melting.
