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
75 words
A PROCESS FOR PREPARING A TAPE WHICH COMPRISES PREPARING A MIXTURE OF A PYROLYZABLE POLYMERRIC BINDER, A SOLVENT FOR SAID BINDER AND A POLYMERIZABLE ORGANIC MEMBER, SAID PYROLYZABLE POLYMERIC BINDER BEING SOLID AT A TEMPERATURE OF ABOUT 40*F. TO ABOUT 120*F. AND SAID POLYMERIZABLE ORGANIC MEMBER BEING POLYMERIZABLE AT OR ABOVE THE PYROLYZING TEMPERATURE OF THE BINDER, APPLYING SAID MIXTURE TO A SURFACE, AND DRYING SAID MIXTURE AT A TEMPERATURE BETWEEN ABOUT 0*C. AND 200*C.
Claim 2
Dependent Claim
75 words
A PROCESS FOR PREPARING A TAPE WHICH COMPRISES PREPARING A MIXTURE OF A PYROLYZABLE POLYMERRIC BINDER, A SOLVENT FOR SAID BINDER AND A POLYMERIZABLE ORGANIC MEMBER, SAID PYROLYZABLE POLYMERIC BINDER BEING SOLID AT A TEMPERATURE OF ABOUT 40*F. TO ABOUT 120*F. AND SAID POLYMERIZABLE ORGANIC MEMBER BEING POLYMERIZABLE AT OR ABOVE THE PYROLYZING TEMPERATURE OF THE BINDER, APPLYING SAID MIXTURE TO A SURFACE, AND DRYING SAID MIXTURE AT A TEMPERATURE BETWEEN ABOUT 0*C. AND 200*C.
Claim 3
Dependent Claim
