Abstract
By mixing and reacting an alkali metal silicate, a substituted monohydroxy organic compound and a polycarboxylic acid and/or polycarboxylic acid anhydride, polyester silicate resinous products are produced which may be utilized as molding powder, coating agent, etc.
Claims20
Process for the production of polyester silicate resinous product by the following steps:
- (a) mixing and reacting the following components, thereby producing a polyester silicate resinous product;
- (i) an alkali metal silicate, 1 to 10 parts by weight;
- (ii) an organic monohydroxy compound having a substituent which will split off during the reaction, 10 to 30 parts by weight;
- (iii) a polycarboxylic acid, polycarboxylic acid anhydride and mixtures thereof, 10 to 30 parts by weight;
- (b) Admixing and reacting a vinyl monomer in an amount of 20 to 50 percent by weight, percentage based on the weight of the polyester silicate resinous product of step (a), and a catalytic amount of a peroxide initiator and activator,
- (c) thereby producing a polyester silicate resinous product.
