| 摘要 |
<p>The invention relates to a hyperbranched polymer comprising a nucleus and polyol and polycarboxy residues, the hyperbranched polymer having at least 6 terminal hydroxyl- or carboxyl groups and a Carothers gel point lower than 1. The hyperbranched polymer having at least 6 terminal hydroxyl- or carboxyl groups, is obtainable by starting with a nucleus compound containing at least one hydroxyl group as the nucleus and reacting it with a compound containing at least one anhydride group, after which the resulting first generation acid-terminated addition product is reacted with a compound containing at least one epoxy group; the resulting first generation hydroxyl-terminated addition product thereafter is reacted, in the second generation, with a compound containing at least one anhydride group, after which the resulting second generation acid-terminated addition product, is reacted with a compound containing at least one epoxy group, resulting in a second generation hydroxyl-terminated addition product, and in at least one generation monomers are used that have at least one functional group besides the anhydride group or epoxy group.</p> |
