    摘要: A process for the production of an alkyl methacrylate, particularly methyl methacrylate, is provided, in which a Baeyer-Villiger Monooxygenase enzyme is used to convert an alkylisopropenylketone substrate to the relevant alkyl methacrylate by abnormal asymmetric oxygen insertion. The invention provides a biobased route to key industrial monomers in particular for the generation of polymers such as poly methyl methacrylate.

    摘要: The present invention provides a resin composition for a golf ball and a golf ball which have high resilience while maintaining soft compression and also have low spin on driver shots, and therefore can achieve a long flight distance. The present invention relates to a resin composition for a golf ball, including an ionomer resin consisting of a metal ion-neutralized copolymer of (A) a C3-8 α,β-unsaturated carboxylic acid and (B) a C3-8 α,β-unsaturated carboxylic acid ester, the ionomer resin having a mass ratio of (A)/(B) of 10/90 to 25/75, and a degree of neutralization of 30 to 105 mol %.

    摘要: A planarizing film-forming composition for a hard disk that is a non-magnetic filler is sufficiently filled into fine grooves on a magnetic material surface (surface), and is required not to cause contraction in the filled parts at the time of photo-curing (at the time of exposure) and post-exposure baking; and a method for producing a hard disk using the composition. The composition comprising at least one polyfunctional (meth)acrylate compound being in a liquid state at room temperature and atmospheric pressure and having a molecular weight of 300 to 10,000. The compound preferably has 2 to 20 (meth)acrylate groups in the molecule, or the compound preferably has a molecular weight of 300 to 2,300. A method for producing a hard disk comprising: forming a concave-convex shape on the surface; covering the surface having the concave-convex shape with the composition; and etching the covered surface for planarization until the surface is exposed.
