    Abstract: A pattern forming method includes forming a coating film containing a hydrophilic first homopolymer having a first bonding group and a hydrophobic second homopolymer having a second bonding group capable of bonding with the first bonding group, forming a bond between the first and second bonding group to produce a block copolymer of the first and second homopolymers, and heating the coating film to microphase-separating the copolymer into a hydrophilic domain and a hydrophobic domain. The hydrophilic and hydrophobic domains are arranged alternately. The bond is broken, then selectively dissolving-removing either domain by a solvent to provide a polymer pattern of a remainder domain.

    Abstract: The present invention provides methylene beta-diketone monomers, methods for producing the same, and compositions and products formed therefrom. In the method for producing the methylene beta-diketones of the invention, a beta-diketone is reacted with a source of formaldehyde in a modified Knoevenagel reaction optionally in the presence of an acidic or basic catalyst, and optionally in the presence of an acidic or non-acidic solvent, to form reaction complex. The reaction complex may be an oligomeric complex. The reaction complex is subjected to further processing, which may be vaporization by contact with an energy transfer means in order to isolate the beta-diketone monomer.

    Abstract: Ethylenically unsaturated, particularly acrylic, monomers are polymerised using a catalyst system including a manganese carbonyl initiator, an organic halogen reactive substrate and an allylic halide chain termination agent. Desirably the manganese carbonyl initiator is a dimanganese compound, particularly dimanganese decacarbonyl (Mn2(CO)10). The catalysis mechanism appears to involve initiator homolysis, abstraction of halogen from the reactive substrate forming an organic free radical which acts as a chain initiator for polymerisation and eventual reaction of the propagating chain radical with the chain terminating agent. The speed or extent of reaction may be modified by the inclusion of Lewis acids in the reaction mixture. The resulting polymers are telechelic and may have different end groups. The polymers can be reacted further to functionalise them and/or to form block copolymers.

    Abstract: A butyl rubber ionomer having improved adhesion to substrates whose surfaces have polar functional groups. Examples of such substrate materials include stainless steel, glass, mylar or Teflon®. The adhesion of the butyl rubber ionomer to the substrate is at least 25% greater than the adhesion of a non-ionomeric butyl rubber to the same substrate surface and with certain substrates is more than 150% greater. The adhesion is improved with increasing levels of multiolefin content in the butyl rubber ionomer. The adhesion is greatest for butyl rubber ionomers having a high multiolefin content (at least 3.5 mol% of multiolefin monomers or at least 1.5 mol % of residual multiolefins). By taking advantage of these high adhesion levels, a composite article can be formed between the butyl rubber ionomer and the substrate.

  • Publication number: 20090130469
    Abstract: A powder adhesive composition for bonding an elastomer to metals or other rigid substrates comprising a powdered film forming polymer having a liquefaction temperature above room temperature and is capable of forming rubber tearing bonds between an elastomer and a substrate. The adhesive composition is shelf stable and free flowing at room temperature to allow for ease of storage and electrostatic spray application, yet melts or flows at elevated temperatures to form a film on a coated substrate prior to elastomer bonding.

  • Patent number: 7473746
    Abstract: A process for polymerizing unsaturated monomers is disclosed. The process comprises polymerizing, in the presence of a late transition metal catalyst (LTMC), a variety of unsaturated monomers which are traditionally, some of which are exclusively, made by free radical polymerizations. The LTMC polymerization provides the polymer with improved properties such as no free radical residue and narrow molecular weight distribution.
