Abstract: Coating composition comprising an oxidatively drying binder and a reactive diluent. The diluent is an ester of a polyunsaturated alcohol, the ester being without chain-end double bonds. The alcohol can selected from the group comprising geraniol, nerol, citronellol, and farnesol. The ester can be a di-ester of a dicarboxylic acid, such as malonic acid or a polyester comprising at least one terminal malonate group.

Abstract: A lithium secondary battery including a positive electrode, a negative electrode, a separator for separating the positive and negative electrodes, and a non-aqueous electrolyte. The separator includes a porous film formed of a mixture of a ceramic material and a binder, and the binder is formed of acrylic rubber having a three-dimensional crosslink structure. The separator provides excellent safety characteristics such as resistance to a short circuit and thermal resistance. Also, the separator improves a high-rate discharge characteristics and increases the life span.

Abstract: A two-component mortar composition is described with a curable resin component containing at least one free radical-polymerizable resin, fillers, reactive diluents, solvents, accelerators and/or further conventional mortar components and, separated therefrom to inhibit reaction, a curing agent component for chemically fastening anchoring means in boreholes, characterized in that the resin component, in order to improve the adhesion to different mineral substrates of the borehole, contains a reactive diluent mixture of at least one hydroxyalkyl (meth)acrylate and at least one acetoacetoxyalkyl (meth)acrylate. Furthermore, the use of the two-component mortar composition for chemically fastening anchoring means in boreholes of different mineral substrates is also described.

Abstract: The present invention is intended to provide a branched polyolefin having various excellent properties, a process for preparing the branched polyolefin and a thermoplastic resin composition containing the branched polyolefin. This branched polyolefin comprises an olefin chain (A) and olefin chain(s) (B) which have recurring units obtained from at least one olefin as main constituent units. In the branched polyolefin, the olefin chain (B) is linked to a position other than both ends of the olefin chain (A), and at least one olefin chain (B) per one olefin chain (A) is present. The process for preparing a branched polyolefin comprises allowing a functional group-containing polyolefin (C) having one or more carboxyl groups and/or acid anhydride groups at positions other than both ends to react with a terminal modified polyolefin (D) having a group capable of reacting with a carboxyl group or an acid anhydride group at only the position of chain end.

Abstract: The invention relates to a coating material containing a binding agent and a cross-linking agent as well as a thixotropic agent based on ureas and/or ureas derivatives, whereby the coating material additionally contains a wetting agent that improves the wettability of the thixtropic agent.

Abstract: A practical polymerizable unsaturated polyester resin composition is provided, wherein a polyester skeleton derived from collected PET is introduced, for effective utilization of waste PET such as a PET bottle which has recently been considered a large obstacle to environmental protection. The polymerizable unsaturated polyester resin composition comprises a straight-chain polyester (A) having a (meth)acryloyl group at both ends of molecules and an ethylenically unsaturated monomer (B), said straight-chain polyester (A) having a (meth)acryloyl group at both ends of molecules being obtained by reacting: (a) a terephthalate oligomer having a hydroxyl group at both ends of molecules resulted from the alcoholysis reaction of collected waste polyethylene terephthalate by an aliphatic glycol having an ether bond, (b) a dibasic acid containing an aromatic dibasic acid as a principal component, and (c) a glycidyl meth)acrylate.

Abstract: A binder for a coating composition is obtainable as the reaction product of a carboxyl-terminated fatty acid ester with an ethylenically unsaturated carboxylic acid and an ethylenically unsaturated carboxylic acid ester. The carboxylic fatty acid ester is produced by reaction of an autoxidisable fatty acid and a polyol, with modification to introduce at least one terminal carboxyl group. The reaction is optionally effected in an organic solvent which is substantially removed at the end. The material is neutralized with a base to render it water-soluble. Thixotropy can be endowed by an amine/(poly)isocyanate final reaction stage to prior neutralization.
