Compositions Containing Copolymers
The invention relates to compositions that contain A) one or more copolymers, said copolymers containing one or more structural units obtained from a) 19.9 to 75.9 wt. % glycerin, b) 0.1 to 30 wt. % at least one dicarboxylic acid, and c) 24 to 80 wt. % at least one monocarboxylic acid according to formula (I) R 1 —COOH (I), in which R 1 is (C 5 -C 29 )-alkyl; (C 7 -C 29 )-alkenyl; phenyl; or naphthyl, and B) one or more solvents that are not miscible with water. The invention is characterized in that said compounds either do not contain water or contain water in a quantity less than or equal to 1.0 wt. % with respect to the total weight of the respective composition. The compositions are advantageously suitable for producing pesticide compositions for example.
1 . A composition comprising
A) at least one copolymer, where the at least one copolymer contains at least one structural unit derived from
a) 19.9 to 75.9% by weight of glycerol
b) 0.1 to 30% by weight of phthalic acid and
c) 24 to 80% by weight of coconut fatty acid
and are prepared by firstly condensing monoglycerol to give an oligo- or polyglycerol and only then reacting it with the phthalic acid and the coconut fatty acid
and
B) at least one water-immiscible solvent,
wherein the composition either comprises no water or comprises water in an amount of less than or equal to 1.0% by weight, based on the total weight of the composition.
2 . The composition as claimed in claim 1 , wherein the at least one water-immiscible solvent is solvent naphtha, fatty acid dimethylamides, vegetable oils, mineral oils or methyl esters of fatty acids of vegetable or animal origin.
3 . The composition as claimed in claim 1 , wherein
