摘要:
There is disclosed a water-soluble coating composition having excellent properties including corrosion resistance, adhesion, impact resistance and so on. The coating composition comprises an adduct of a butadiene lower polymer or copolymer and .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid compound resulting from the special addition reaction, a hydrophilic solvent and a neutralizer.
摘要:
In a method for preparing an adduct of (A) a butadiene lower polymer or butadiene lower copolymer and (B) a .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid compound, said method is characterized in that said (A) and (B) are caused to react in the presence of one or more compounds selected from (C) p-phenylenediamine derivatives, catechol derivatives, pyrogallol derivatives, N-nitrosamines, quinoline derivatives and naphthol derivatives, thus serious increase of the viscosity of said adduct in the addition reaction can be prevented.

摘要:
A coating composition is disclosed which is curable at room temperature uniformly at and through the surface and inner portions of a film formed upon application of the composition to an article. The coating composition is characterized by the combination with a starting butadiene polymer (to which an acid is added) of a poly-(metha)-acrylate of a polyhydric alcohol, at least one of the compounds which have an allyl ether group, a tetrahydrofurfuryl group or a benzyl ether group, a radical generator and, if desired, a pigment.

摘要:
When a lower polymer of butadiene or a lower copolymer of butadiene with a conjugated diolefin other than butadiene or a vinyl-substituted aromatic comonomer is reacted at 0 to 200.degree. C. in the presence of a combination catalyst including an organic alkali metal compound and a specific diamino compound, the non-conjugated double bonds are effectively isomerized to the conjugated diene double bonds at a very high conversion, and a polymer having a high reactivity, which is useful as a paint vehicle, a thermosetting material, an adhesive, a rubber compounding material and an intermediate for various synthetic reactions, can be obtained.
