Abstract
Abstract There is disclosed the in situ synthesizing of a polymeric material on a substrate by applying to the substrate a solid pyrolyzable binder which contains at least one member capable of polymerizing at or above the pyrolysis temperature of the binder and then applying heat so as to pyrolyze the binder and synthesize the polymer such that the pyrolyzed binder is not a part of the in situ synthesized polymeric material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
A PROCESS FOR BONDING TWO OR MORE SURFACES TOGETHER, WHICH PROCESS COMPRISES APPLYING TO A FIRST SURFACE A COMPOSITION WHICH CONSISTS ESSENTIALLY OF A SOLID PYROLYZABLE POLYMERIC BINDER, A SOLVENT FOR THE BINDER, AND AT LEAST ONE POLYMERIZABLE ORGANIC MEMBER, CONTACTING THE COMPOSITION CONTAINING FIRST SURFACE WITH A SECOND SURFACE SO AS TO FORM A LAMINATE-LIKE STRUCTURE, AND HEATING THE STRUCTURE SO AS TO REMOVE THE PYROLYZABLE BINDER AND SYNTHESIZE IN SITU A POLYMERIC MATERIAL, SAID MATERIAL ACTING AS AN ADHESIVE SUCH THAT THE SURFACES ARE BONDED TOGETHER.
Claim 2
Dependent Claim
88 words
