Abstract
The invention relates to a process for the grafting of unsaturated monomers to the surface of glass substrates. The process comprises applying to the glass substrates a solution comprising a silane having a double ethylene bond, contacting the products thus coated with an atmosphere formed by a mixture of ozone and oxygen, and placing these coated products in contact with an unsaturated organic monomer. The monomer may be added in the form of a solution, an emulsion or a suspension. The products thus obtained may have a number of technical applications.
Claims20
A process for forming a coated glass substrate comprising:
- applying to a surface portion of said substrate a solution comprising a silane having a double ethylene bond to form a substrate coated with said silane solution;
- contacting said coated substrate with an atmosphere comprising a mixture of oxygen and ozone so as to convert said silane coating to an ozonide;
- and
- contacting said ozonide coated substrate with an unsaturated monomer so as to graft said unsaturated monomer to the surface of said substrate and thus form a coating thereof upon said substrate.
