  • Patent number: 7897718
    Abstract: The present invention relates to an acrylated semi-crystalline hyperbranched polyurethane oligomer and a preparation method thereof, which is characterized in that on the basis of the synthesis of hyperbranched polyurethane oligomer, it adopts a two-step process to make modifications to form a methacrylic and/or acrylic double bond and a long carbon chain with a carbon atom number higher than 10 or a benzene ring or a naphthalene ring at the terminals. The obtained oligomer has a lower melting point and a higher glass transition temperature and can be cured by means of radiation, and the curing rate is high enough to effectively improve production efficiency and save energy to form a cured film having a higher hardness and excellent thermal stability. The raw materials used in the method of the invention are easily obtained, and the method is suitable for large-scale production in industry.

  • Patent number: 7893184
    Abstract: Dendritic or hyperbranched polyurethanes are prepared by 1) reacting diols or polyols having at least one tertiary nitrogen atom and at least two hydroxyl groups of differing reactivity toward isocyanate groups with diisocyanates or polyisocyanates to form an addition product, with the diols or polyols and diisocyanates or polyisocyanates being selected so that the addition product has, on average, one isocyanate group and more than one hydroxyl group or one hydroxyl group and more than one isocyanate group, 2) converting the addition product from step 1) into a polyaddition product by intermolecular reaction of the hydroxyl groups with the isocyanate groups, and with a reaction with a compound containing at least two hydroxyl groups, mercapto groups, amino groups or isocyanate groups also being able to be carried out first, 3) if desired reacting the polyaddition product from step 2) with a compound containing at least two hydroxyl groups, mercapto groups, amino groups or isocyanate groups.

  • Patent number: 7790907
    Abstract: A method produces a uretonimine-modified isocyanate composition having increased low-temperature tolerance. The method comprises providing a first polyisocyanate composition having two or more isocyanate groups and comprising 4,4?-diphenylmethane diisocyanate (MDI) and reacting the first polyisocyanate composition at a temperature of from about 90° C. to about 115° C. and in the presence of a catalyst such that the isocyanate groups form carbodiimides for forming uretonimine and uretonimine oligomers. The reaction of the first polyisocyanate composition is quenched with a quenching agent to produce an intermediate composition having an intermediate isocyanate value of from about 21.0 to about 26.0. The intermediate composition is blended with a second isocyanate composition to form a stable uretonimine-modified isocyanate composition.
