    Abstract: PROBLEM TO BE SOLVED: To obtain a sticky polyolefin composition having improved adhesivity to various substrates by adding a specific adhesion accelerator to a polyolefin containing a curing agent. SOLUTION: This sticky polyolefin composition comprises (A) a polyolefin having at least two ethylenic unsaturated substituents capable of curing the polyolefin and (B) an adhesion accelerator comprising (i) an epoxide-containing compound (preferably 3-glycosidoxypropyltrimethoxysilane, etc.), selected from organic compounds and organic silicon compounds and (ii) a compound (preferably dihydrocarveol) having a substituent selected from a silanol (=SiOH), a hydrolyzable silanol precursor and a carbinol (=COH) and a substituent capable of reacting during the curing of the component A. The component B is added in a content of 1.5-7.5 wt.% based on the total weight of the composition. The component i is used in an amount of 10-90 wt.% based on the total amount of the components i and ii.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject copolymer having reduced unpleasant smell by exposing a reaction product of a mixture composed of a specific polyether compound, a specified copolymer and a prescribed hydrosilylation catalyst to a hydrogen gas under a specific condition. SOLUTION: (A) A mixture comprising (i) an alkenyl functional polyether compound, (ii) a polydiorganosiloxane polyorganohydrogensiloxane copolymer (preferably a polydimethylsiloxane-polymethylhydrogensiloxane copolymer containing a trimethylsiloxy end) and (iii) a homogeneous transition metal hydrosilylation catalyst is reacted and (B) the reaction product of the process A is exposed to a hydrogen gas at 20-200 deg.C under 6.9×101 to 1.38×103 kPa for 0.1-48 hours. The preferable amounts of the components in the mixture of the process A are 1-99 wt.% of the component (i) and 1-99 wt.% of the component (ii). The amount of the component (iii) is an amount enough to provide 0.01-100 pts.wt. of a transition metal based on 1,000,000 pts.wt. of the component (i).

    Abstract: PROBLEM TO BE SOLVED: To obtain a poluolefin composition capable of exhibiting storing binding forces to various substrates by mixing a polyolefin with a specific organic silicon compound as an adhesive-accelerating agent. SOLUTION: This polyolefin composition comprises (A) at least one polyolefin which contains repeating units derived from at least one olefin and functional groups capable of cross-linking the polyolefin, and (B) an effective amount of an adhesive-accelerating agent. The component B is the reaction product of a polyhydric alcohol of formula I [R1 is a m-valiant hydrocarbon containing no ethylenic unsaturated group or the like; and (m) is an integer of at least 2] with a silane of formula II [R2 is a non-substituted hydrocarbon or the like; (n) is 0 or 1; and X is a hydrolyzable group] or a bissilylalkane of formula III (R3 is an alkylene). The composition shows adhesivity to inorganic and organic substrates.
