Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
A PROCESS FOR TREATING AN ORGANIC, POLYMERIC, THERMOPLASTIC SHAPED STRUCTURE OF A FLUOROCARBON POLYMER CONTAINING AT LEAST 5 MOLE PERCENT OF RECURRING STRUCTURAL UNITS HAVING THE FORMULA: -(CH(-X2)-CF(-X1))WHEREIN: -X1 IS A MONOVALENT RADICAL SELECTED FROM THE GROUP CONSISTING OF -H, -F, -CL AND CF3; AND -X2 IS A MONOVALENT RADICAL SELECTED FROM THE GROUP CONSISTING OF -H, -F, -R1 AND -$2, WHEREIN R1 IS SELECTED FROM THE GROUP CONSISTING OF ARYL AND ALKYL HAVING 1 TO 8 CARBON ATOMS AND -R2 IS SELECTED FROM THE GROUP CONSISTING OF -O-R1, -CH2-O-R1, -CO-R1, -CH2-CO-R1, -COO-R1, -OOC-R1, AND -CH2-OOC-R1 WHICH COMPRISES CONTACTING A SURFACE OF SAID STRUCTURE OF SAID FLUOROCARBON POLYMER WITH AN AMOUNT OF BORON TRIFLUORIDE AND OXYGEN SUFFICIENT TO IMPROVE THE SURFACE ADHERABILITY OF SAID STRUCTURE.
