A reaction product is obtained by free-radical emulsion polymerization in an aqueous medium of ethylenically unsaturated monomers including at least one conjugated diene. The free-radical emulsion polymerization is conducted in the presence of a degraded polysaccharide having a DE of 38 to 70 measured according to ISO 5377 (1981 Feb. 15) and optionally an alkyl mercaptan in an amount of no more than 2.5 weight percent based on the total weight of ethylenically unsaturated monomers. A coating composition includes the reaction product, and a paper or a board can be coated with such a coating composition.

The invention relates to heat-curing reactive compositions based on natural and/or synthetic liquid elastomers containing olefinic double bonds and on vulcanizing agents, where these comprise a quantity, relative to the entire composition, of from 1 to 25% by weight, preferably from 1 to 15% by weight, of at least one liquid polyisoprene, preferably at least one cis-1,4 polyisoprene; a quantity, relative to the entire composition, of from 0.5 to 10% by weight, preferably from 0.5 to 5% by weight, of at least one functionalized liquid polybutadiene; a quantity, relative to the entire composition, of up to 40% by weight, preferably from 1 to 25% by weight, of a triglyceride fraction, the distribution of fatty acid in which comprises a proportion of at least 5% by weight, more particularly at least 60% by weight, of one or more omega-3 fatty acids and/or one or more omega-6 fatty acids; and at least one vulcanizing agent, where the proportion, relative to the entire composition, of synthetic polymers having at least one CC double bond and/or at least one CC triple bond is at least 7.5% by weight, preferably 9% by weight. These have plastisol-like rheology and therefore can be applied at room temperature by conventional spray systems. The invention also relates to use of same as sealant composition or as coating composition, and to methods for bonding components and/or sealing joints between components and/or coating components with use of the compositions.

A coating agent for oil seal comprising 10 to 160 parts by weight of a filler having a particle size of 0.5 to 30 m based on 100 parts by weight of isocyanate group-containing 1,2-polybutadiene and being prepared as an organic solvent solution, wherein a contact angle between a substrate surface coated with the coating agent and engine oil is less than 35. The coating agent can improve wettability with oil and reduce dynamic friction coefficient in oil, while increasing the roughness of the coating surface. Thus, low torque characteristics can be achieved, while maintaining excellent seal performance inherent in oil seal.

A weather resistive barrier (WRB) for the exterior protection of building substrates can have a water vapor permeability that decreases with increasing temperature. In an embodiment, the WRB includes a coating comprising a LCST polymer, and may further include a second polymer. The WRB can be part of a building assembly, part of a sheet, or a sheet itself, the sheet having an air permeability of less than 0.02 L/(s m.sup.2) at a pressure of 75 Pa. Furthermore a liquid coating composition can include a LCST polymer and a second polymer, wherein the liquid coating composition can be adapted that a solid coating formed by the liquid coating composition has an air permeability of less than 0.02 L/(s m.sup.2) at a pressure of 75 Pa and a water vapor permeability that decreases with increasing temperature.
