    Abstract: A process for preparing a branched polymer, belonging to the fields of polymer synthesis and preparation of functional polymers. A vinyl monomer, such as styrene, toluene (benzene, xylene) as a solvent, is subjected to a self-initiated free radical polymerization at 60˜100° C. with a new type of compound (methyl (meth)acrylate peroxide) as the initiator and the branched monomer containing both polymerisable double bond and peroxide bond, which can be used to synthesize the branched polymers. The degree of branching of the polymer can be adjusted by adjusting the molar ratio of the new type of compound to polymerisable monomer. The process for preparing a branched polymer is carried out under the conditions of conventional free radical polymerization without the addition of the branched monomer and other assist initiators.

  • Publication number: 20080299503
    Abstract: The formation of high-resolution resist patterns by liquid immersion lithography with various fluids is enabled by protecting a resist film from deterioration (such as bridging) during the immersion exposure in a fluid (such as water) and the fluid from deterioration and improving the stability of a resist film in the storage after exposure without increase in the number of treatment steps. A material for forming resist protection films which comprises an alkali-soluble polymer for forming a protective overcoat for a resist film, characterized in that the contact angle of the polymer to water is 90° or above. The polymer is preferably an acrylic polymer which comprises as the essential components constituent units derived from (meth) acrylic acid and constituent units derived from a specific acrylic ester.

  • Patent number: 7354972
    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.
