摘要:
A comb polymer can be used for reducing a Noack evaporation loss of a lubricant composition, especially of an engine oil composition. Application of the comb polymer to the lubricant composition can bring about the desired reduction. The comb polymer can include specified amounts of macromonomer and alkyl acrylates. Resulting lubricant compositions can include the comb polymer.

A liquid photocurable resin composition contains a (meth)acrylate oligomer component, an alkyl (meth)acrylate monomer component, and a photopolymerization initiator component. The (meth)acrylate oligomer component contains at least one oligomer selected from the group consisting of a polyurethane (meth)acrylate oligomer, a polyisoprene (meth)acrylate oligomer, a polybutadiene (meth)acrylate oligomer, and a polyether (meth)acrylate oligomer that have a weight average molecular weight of 1,000 to 200,000. The photopolymerization initiator contains a molecule cleavage-type photoradical polymerization initiator and a hydrogen-abstracting photoradical polymerization initiator at a ratio by mass of 10:1 to 10:35. The cured resin that is obtained by photoradical polymerization of the photocurable resin composition has a glass transition temperature of −40 to 20° C. when the composition is cured at a curing ratio of the outermost surface of more than 90%.

摘要:
UV curable, liquid, oligomeric compositions are prepared from the reaction product of a Michael addition oligomer and an isocyanate capped polybutadiene. The UV curable, liquid, oligomeric compositions can be cured in the presence of fragrances to form articles that are characterized by a controlled release of the fragrance over time.
摘要:
The present invention provides a photosensitive resin composition and a photosensitive dry film resist produced therefrom, and further provides a photosensitive dry film resist having excellent flame-retardant properties. More specifically, the present invention provides a photosensitive dry film resist and photosensitive coverlay film produced from a photosensitive resin composition consisting mainly of soluble polyimide, a compound having a carbon-carbon double bond, and a photoreactive initiator and/or sensitizer that have excellent workability, can be developed in an alkaline solution, and meet the standard for tests for flammability of plastic materials known as UL94V-0. The photosensitive coverlay film of the present invention can be attached without any adhesives and has an excellent heat resistance, so that it is suitably used for a printed wiring board to be used in the electronic material field, for hard disc suspension, and for a hard disc head for a personal computer.
