    Abstract: Process for the manufacture of hardenable copolymers by the polymerization of unsaturated esters with unsaturated polymerizable monomers containing no free COOH groups, wherein an olefinically unsaturated diester containing OH groups is used as the unsaturated ester, said diester being obtained by reacting olefinically unsaturated dicarboxylic acids or the anhydrides thereof with a polyhydric alcohol and a monoepoxide compound in one or more steps, characterized in that the copolymerization of the diesters with monomers which contain no free COOH groups is carried out in the presence of copolymerizable monomers containing free COOH groups, and the use of the copolymers as hardenable binders for lacquers and/or coating compositions.

    Abstract: A process for the preparation of copolymers in which in a first step an olefinically unsaturated dicarboxylic acid is reacted with a polyhydric alcohol to yield a hemi-ester having free hydroxyl groups, which in a second step is reacted with a monoepoxy compound to yield an olefinically unsaturated diester containing hydroxyl groups, wherein the diester is copolymerized in at least one further step with at least one unsaturated monomer having no free carboxyl groups, and the hardenable reaction product thus obtained is either isolated or hardened with a hardening agent, and coating and adhesive compositions containing a copolymer thus obtained.

    Abstract: An air-drying alkyd resin comprising (I) at least one alpha , beta -olefinically unsaturated dicarboxylic acid unit or a mixture thereof with (I') a polycarboxylic acid unit being free from polymerizable olefinic and acetylenic bonds, said units bound as an ester, (II) at least one trihydric alcohol unit or a combination thereof with a minor amount of a dihydric alcohol unit, (III) from 10 to 35% by weight (referred to the total alkyd resin) of cyclopentadiene units and (IV) at least one predominantly aliphatic monocarboxylic acid unit, wherein the amount by weight of monocarboxylic acid units is at least as large as the total amount of polycarboxylic acid units, the latter being calculated as anhydride and a process of preparation said resin.
