Abstract
Polyamide silicate resinous products are produced by reacting halosilicon acids with a polyamine compound and a polycarboxylic acid and/or polycarboxylic anhydride. The polyamide silicate resinous products may be utilized as molding powders, as films, as sheets, as coating agents, as caulking compounds, as an adhesive and in the production of polyurethane silicate resins and foams.
Claims10
The process for the production of polyamide silicate resinous product modified with vegetable oil by mixing and reacting the following components:
- (a) halosilicon acids, 0.5 to 1 mol, produced by reacting 0.5 to 2 mols of hydrated silica compound with 1 mol of a silicon halide;
- the mols of halosilicon acid are based on the mols of silicon halide used;
- (b) organic polyamine, 1 to 2 mols;
- (c) polycarboxylic acid, polycarboxylic acid anhydride or mixtures thereof, in a total amount of 1 to 2 mols;
- (d) vegetable oil, in an amount wherein a portion of the polycarboxylic acid or polycarboxylic acid anhydride is replaced with a vegetable oil.
