The present application relates to a method for preparing compounds of the formula I in which, in a first step, &#x3b3;-butyrolactone is reacted with diamines of the formula II to form bisamides of the formula Ill, with the amide function of the bisamides of the formula Ill then undergoing partial or complete catalytic hydrogenation in step II) to form bispyrrolidine compounds of the formula I.

Method for producing bispyrrolidine compounds

What are described are compounds having two or more exovinylene cyclocarbonate units, wherein the exovinylene cyclocarbonate units are bonded to one another via at least one organic, siloxane-free connecting group which is not bonded directly to the exovinylene double bonds, excluding connecting groups formed by polymerization of (meth)acrylic monomers. The connecting group preferably has at least one acetal group. Also described are a process for preparing the compounds, two-component binders comprising the compounds, and uses of the compounds.

Process for preparing epoxycarboxylic esters

A process for curing an epoxy resin composition containing an epoxy resin and a compound of the general formula I: where Rand Rindependently are hydrogen, C-C-alkyl, C-C-alkoxy-C-C-alkyl, C-C-cycloalkyl, phenyl, phenyl-C-C-alkyl, C-C-alkenyl or C-C-alkynyl, or Rand Rtogether are a C-C-alkylene group; and where Rand Rindependently are hydrogen, C-C-alkyl, C-C-alkoxy-C-C-alkyl, C-C-cycloalkyl, phenyl, phenyl-C-C-alkyl, C-C-alkenyl or C-C-alkynyl, or Rand Rtogether are a C-C-alkylene group. The process includes adding amino hardeners, where 0.1% to 50% by weight of the amino hardeners are aliphatic, cycloaliphatic or aromatic amine compounds having 1 to 4 primary amino groups and optionally further functional groups, selected from secondary amino groups, tertiary amino groups, and hydroxyl groups. In the case of the cycloaliphatic and aromatic amine compounds, the primary amino groups are attached as aminomethylene groups (HN&#x2014;CH&#x2014;) to the cycloaliphatic or aromatic ring system (referred to below for short as co-hardeners).
