Abstract
A high-molecular weight polyorganosilyl silicate having a weight-average molecular weight of 30,000 to 2,000,000 on polystyrene conversion in which the repeating units form a ladder structure through siloxane bonding, and the ladder structures are further bonded together through siloxane bonding is disclosed. Also disclosed is a process for producing the polymer. The polymer is useful as a coating material or a film-forming material to provide a coating film or a film having excellent electrical characteristics, weather resistance, adhesion, water repellency, processability and scratch resistance.
