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: 7
Claim 1
Independent Claim
41 words
The process of claim 1, wherein the pyrolyzable binder is selected from polyethers, poly(alkyl methacrylates), methacrylate copolymers, polyisobutylene, poly(trimethylene carbonate), poly(beta-propiolactone), poly(delta-valerolactone), poly(ethylene carbonate), poly(propylene carbonate), poly(ethylene oxalate), vinyl toluene/alpha-methyl styrene copolymers, styrene/alpha-methyl styrene copolymers, cellulose ethers, and olefin-sulfur dioxide copolymers.
Claim 2
Dependent Claim
33 words
The process of claim 1, wherein the polymerizable organic member comprises at least one compound selected from difunctional, trifunctional, and polyfunctional organic amines, carboxylic acids, esters, isocyanates, alcohols, phenols, acyl halides, and hydrazides.
Claim 3
Dependent Claim
34 words
The process of claim 1, wherein the polymerizable organic member comprises at least one substance selected from epoxy resins, ureaformaldehyde resins, phenol-formaldehyde resins, melamine-formaldehyde resins, furan resins, polyanhydrides, polyhydrazines, polyethers, polesters, and silicone resins.
Claim 4
Dependent Claim
18 words
The process of claim 1 wherein the polymerizable organic member contains at least one organic anhydride or dianhydride.
Claim 5
Dependent Claim
21 words
The process of claim 1, wherein the polymerizable organic member is a mixture of an organic diamine and an organic dianhydride.
Claim 6
Dependent Claim
22 words
The process of claim 1, wherein the polymerizable organic member is a mixture of a tetrafunctional organic amine and an organic diester.
Claim 7
Dependent Claim
72 words
A process of in situ synthesizing a polymeric material on at least one substrate which comprises: applying to the substrate a solid pyrolyzable binder containing 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 polymeric material, such that the pyrolyzed binder is not a part of the in situ synthesized polymeric material.
