Abstract
The invention relates to ionic polymers obtained by reaction of carboxyfunctional fat- and oil-based starting materials with salts of polyvalent ions. They may be used as sealants, coatings, adhesives and as additives for plastic formulations and for mortars, gypsums and cements. The starting mixture may be present both in a one-component formulation and in a two-component formulation.
Claims15
Ionic polymer produced by the reaction of polyvalent metal ions with a member selected from the group consisting of an oligomer containing fatty acid residues and at least one reactable carboxyl group per oligomer molecule having a molecular weight above 200 and a mixture of said oligomer with up to 30% by weight, of said mixtures of a carboxylic acid having a molecular weight not higher than 200, to form salt bridges, said fatty acid residues of said oligomers being based on fats and oils.
A one-component, moisture-curable mixture useful for the production of an ionic polymer comprising an anhydride of a metal salt of a polyvalent metal ion and carboxylic acids and an anhydride of a carboxylic acid, said carboxylic acids being based on fats and oils and having a molecular weight of greater than 200 for at least 70% by weight of said carboxylic acid.
A process for the production of ionic polymers, said process comprising;
- reacting polyvalent metal ions and a member selected from the group consisting of an oligomer containing fatty acid residues and at least one reactable carboxyl group per oligomer molecule having a molecular weight above 200 and a mixture of said oligomer with up to 30% by weight, of said mixture of a carboxylic acid having a molecular weight not higher than 200, to form salt bridges, said fatty acid residues of said oligomers being based on fats and oils.
