A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected, such that the modified polymer deblocks at temperatures of at least 100 C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.

The present invention provides a composition for a soft urethane foam to prepare a soft urethane foam, comprising a polyol, and a foamed soft urethane foam using the same, wherein the polyol is any one selected from among a hydrocarbon polyol, a vegetable oil, and a vegetable-oil-derived dimer acid, or a mixture of a hydrocarbon polyol with any one selected from among a vegetable oil and a vegetable-oil-derived dimer acid. The present invention provides an impregnation material for impregnation of a cosmetic composition, which can control the polarity of the impregnation material for impregnating a hydrophilic cosmetic composition, and an impregnation-use urethane foam composition for preparing the same.

A two-component polyurethane composition made of a polyol component and a polyisocyanate component, wherein the polyol component includes at least one reaction product of castor oil with ketone resins A1, at least one aliphatic triol A2, an aliphatic diol A3, and a polybutadiene polyol A4. The polyurethane composition has high strength and only a minor dependence of mechanical properties, especially of strength, on temperature, especially in the range from 60 C. to +60 C. Moreover, the composition is capable of curing without blistering under ambient conditions, even in the presence of substrates that typically promote foaming reactions owing to the presence of residual moisture, for example glass fiber weave.
