摘要:
The present invention relates to a thermoplastic block copolymer comprising at least one PA block and at least one PB block. The PA block represents a polymer block comprising one or more units of monomer A, and the PB block represents a polymer block comprising one or more units of monomer B. Monomer A is a vinyl, acrylic, diolefin, nitrile, dinitrile, acrylonitrile monomer, a monomer with reactive functionality, or a crosslinking monomer. Monomer B is a radically polymerizable triglyceride or mixtures thereof, typically in the form of a plant or animal oil. The present invention also relates to a method of preparing a thermoplastic block copolymer or novel thermoplastic statistical copolymers by polymerizing a radically polymerizable monomer with a radically polymerizable triglyceride or mixtures thereof via reversible addition-fragmentation chain-transfer polymerization (RAFT), in the presence of an free radical initiator and a chain transfer agent.

An object of the present invention is to provide a curing accelerator for an oxidative polymerization-type unsaturated resin which can decrease the amount of use of a cobalt metal soap and which has curing performance equal to or higher than the excellent curing performance of a cobalt metal soap, and also provide a printing ink and a coating material using the curing accelerator. The present invention provides a curing accelerator, and a printing ink and a coating material containing the curing accelerator, the curing accelerator including a fatty acid manganese salt (A), an aminoalcohol (B) represented by general formula (1) below (in the formula, R 1 and R 2 each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, X 1 and X 2 each independently represent an alkylene group having 2 to 6 carbon atoms, and Y represents -NR 3 - (wherein R 3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms) or an oxygen atom), and at least one fatty acid metal salt (C) selected from the group consisting of a fatty acid bismuth salt, a fatty acid zirconium salt, a fatty acid barium salt, and a fatty acid iron salt.

The invention relates to a wood impregnation method, in which an emulsion is absorbed into wood by means of pressure difference. The emulsion contains a reaction product of a fatty acid obtained from a natural oil and a polyalcohol, an emulgator and water. In this way the dimensional stability and the water repulsion of wood can be physically improved. In addition a good biological durability is achieved.

The present invention provides an oxidatively polymerizable composition which is capable of reducing the used amount of a metal dryer, which is thought to have harmful effects on the environment and living things, and of obtaining a practically sufficient polymerization rate. A present invention provides an oxidatively polymerizable composition including at least one selected from the group consisting of a drying oil, a denatured product of the drying oil, a semi-drying oil, and a denatured product of the semi-drying oil derivative; a lipoxidase; and a metal salt of an organic acid.

Disclosed are dryable stain compositions, such as wiping stains, that include a binder including a mixture of an alkyd resin and a drying and/or semi-drying oil, wherein the stain composition (a) includes no more than 100 grams of volatile organic material per liter of the stain composition, and (b) is substantially free of water. Also disclosed are porous substrates at least partially coated with such stain compositions, methods for staining at least a portion of a porous substrate with such stain compositions, and porous substrates at least partially coated with a multi-layer composite coating system wherein at least one coating layer is deposited from such a stain composition.

The present invention pertains to the uses of HiOmega flax (linseed) oil, a naturally occurring flax (linseed) with higher than normal alpha linolenic acid content in the production of stronger, more scratch and solvent resistant industrial products such as alkyd resins, epoxidized oils, epoxies, inks, coatings such as paints, enamels, varnishes and films and anti-spalling concrete preservatives.
摘要:
The invention relates to a coating material, paint or finish which contains as anti-skinning agents a combination of at least two organic and/or inorganic oxygen scavengers and also relates to compositions containing the combination, especially oxidatively drying paints or coating compositions and articles coated with such oxidatively drying paints or coating compositions.
摘要:
The present invention provides polyolefin compositions that exhibit both stiffness and toughness. Polyolefin compositions according to the invention include a polyolefin homopolymer resin such as polypropylene and an impact modifying fluid that includes a nonionic surfactant and optionally a diluent such as mineral oil. The nonionic surfactant can be an ethoxylated sorbitan fatty acid ester such as ethoxylated sorbitan trioleate. Unfilled impact modified polypropylene homopolymer formed in accordance with the invention preferably exhibits a Gardner impact strength of at least 100 in-Ibs, a flexural modulus of at least 40 kpsi and a tensile modulus of at least 60 kpsi.
