    Abstract: PROBLEM TO BE SOLVED: To obtain a polyisocyanate useful as a building block made of polyurethane and combining high functionality, high reactivity, low consistency and good properties. SOLUTION: (i) An addition product A is produced by reacting a diisocyanate or a polyisocyanate I with a compound having three or more groups reactive to the isocyanate, a compound having two groups reactive thereto or the mixture of the compounds. A reaction ratio is selected so that the product A containing an average of one group having reactivity to the isocyanate. (ii) A polyaddition product P containing an average of one group having reactivity to the isocyanate and an average of more than two isocyanate groups is formed by an intermolecular addition product. (iii) The high functional polyisocyanate is obtained by reacting the product A and/or the product P with a diisocyanate or a polyisocyanate II.

    Abstract: PROBLEM TO BE SOLVED: To provide a polyisocyanate which has good characteristics and can easily by produced. SOLUTION: This method for producing the polyisocyanate, comprising (i) a step for reacting (a) a diisocyanate I (cf. the specification) with (b) a compound having two groups capable of reacting with the isocyanate (wherein, at least one of the components (a) and (b) has a function group exhibiting a reacting property different from the functional groups of the other component) to produce (A) the addition product with having one isocyanate group and a group capable of reacting with one isocyanate, (ii), if necessary, a step for producing (P) a polyaddition reaction product having one isocyanate group and a group capable of reacting with one isocyanate, and (iii) a step for reacting (A) the addition product and/or (P) the polyaddition reacting product with a diisocyanate or polyisocyanate II different from the diisocyanate I.

    Abstract: PROBLEM TO BE SOLVED: To provide a two-component polyurethane contg. a reactive diluent which is easy to manufacture and incorporated into a polyurethane without difficulty, and has no side-reaction with the structural component of the polyurethane. SOLUTION: This polyurethane comprises at least two-functional polyisocyanate component and polyol component, and the polyol component contains at least a cyclic acetal contg. a hydroxyl and/or a ketal. This method of manufacturing the polyurethane comprises a reaction of at least two- functional polyisocyanate with a compd. contg. an active hydrogen, and the compd. contg. an active hydrogen contains the cyclic acetal and/or the ketal as a reactive diluent.

    Abstract: Mixtures containing (a) polyisocyanates (A) with isocyanurate and/or biuret units, derived from aliphatic or cycloaliphatic di-isocyanates (C) and (b) other polyisocyanates (B) with allophanate and/or urethane units, derived from (b1) di-isocyanates (C) as above and (b2) polyhydric aliphatic or cycloaliphatic alcohols (alcohols A'), with a mol ratio of (A):(B) = (200:1)-(5:1). Independent claims are also included for (i) a method for the production of these mixtures by reacting (C) with (A') in a mol ratio of (200:1)-(5:1), optionally in presence of catalysts for the formation of allophanates and urethanes, optionally deactivating the catalyst, optionally removing unreacted (C) and then mixing the resulting (B) with (A) in the above ratio; (ii) an alternative method in which (A) contains mainly isocyanurate units, involving the reaction of (C) with (A') as above, optionally in presence of catalysts for the formation of isocyanurates, allophanates and urethanes; (iii) an alternative method in which (A) contains mainly biuret unit, involving the reaction of (C), (A') and a biuretising agent (D) in mol ratios of (C):(A') = (200:1)-(5:1) and (C):(D) = (200:1)-(5:1), optionally in presence of catalysts for the formation of biurets, allophanates and urethanes; (iv) two-component coating materials containing a polyisocyanate mixture as above and an isocyanate-reactive component; (v) a method for coating objects by mixing the two components (see iv above) and coating the resulting mixture onto the substrate within 12 hours; (vi) coated objects obtained by this method.
