Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A PROCESS FOR THE PRODUCTION OF A FABRIC ADAPTED TO BE BONDED UNDER LOW PRESSURE TO OTHER LIKE FABRIC AND TO THER SURFACES, WHICH COMPRISES TREATING THE FABRIC WITH A NON-POLYMERIZABLE LIQUID COMPOSITION CONSISTING OF A SOLUTION OF A THERMOPLASTIC POLYMER IN AN ORGANIC SOLVENT CONTAINING ALSO AN ORGANIC PEROXIDE SELECTED FROM THE GROUP CONSISTING OF BENZOYL PEROXIDE AND LAUROYL PEROXIDE, AND EVAPORATING THE SOLVENT TO DEPOSIT THE THERMOPLASTIC POLYMER AND THE ORGANIC PEROXIDE IN AND ON THE FABRIC.
Claim 2
Dependent Claim

Claim 3
Independent Claim
102 words
A METHOD OF BONDING FABRIC TO ANOTHER SURFACE, WHICH COMPRISES WETTING A FABRIC LOADED WITH A SOLID THERMOPLASTIC POLYMER AND AN ORGANIC PEROXIDE SELECTED FROM THE GROUP CONSISTING OF BENZOYL PEROXIDE AND LAUROYL PEROXIDE WITH A LIQUID COMPOSITION CONSISTING OF A STABILIZED MONOMERIC POLYMERISABLE LIQUID ESTER WHICH IS COMPATIBLE WITH THE POLYMER AND CAN BE POLYMERISED BY THE CATALYTIC ACTION OF THE SAID PEROXIDE AND CONTAINS A TERTIARY AMINE WHICH REACTS WITH THE SAID PEROXIDE WITH EVOLUTION OF HEAT, AND MAINTAINING THE WETTED FABRIC IN CONTACT WITH SAID OTHER SURFACE UNTIL THE POLYMERISABLE LIQUID ESTER HAS POLYMERISED TO FORM THE DESIRED BOND.
