Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
226 words
A SHAPED STRUCTURE OF A GRAFT COPOLYMER OF FIBERFORMING MOLECULAR WEIGHT COMPRISING (1) A HIGH MOLECULAR WEIGHT, SYNTHETIC LINER POLYMER FROM THE CLASS CONSISTING OF A POLYAMIDE, A POLYURETHANE, A POLYUREA AND A POLYSULFONAMIDE WHEREIN THE AMIDO GROUPS OF THE RECURRING INERUNIT LINKAGES ARE AN INTEGRAL PART OF THE POLYMER CHAIN AND (2) GRAFT COPOLYMERIZED THERETO, FROM AT LEAST 4 TO ABOUT 200 WEIGHT PERCENTAGE, BASED ON THE WEIGHT OF THE ORIGINAL LINEAR POLYMER, OF SUBSTANTIALLY LINEAR HYDROCARBON SIDE CHAINS, EACH SIDE CHAIN BEING ATTACHED BY A SINGLE CARVON-TO-CARBON BOND TO A CATENARIAN CARBON OF THE SAID LINEAR POLYMER, EACH SAID SIDE CHAIN BEARING AS SUBSTITUENTS FOR HYDROGEN RADICALS FROM THE CLASS CONSISTING OF (A) AMIDO RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH CARBONYL CARBON, (B) AMIDO RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH AMIDE NITROGEN, AND (C) LACTAM RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH LACTAM NITROGEN, WITH THE PROVISO THAT ANY OF THE SAID SUBSTITUENTS (A), (B) AND (C) HAS A MIXIMUM CARBON ATOM CONTENT OF 6 AND WITH THE FURTHER PROVISO THAT THERE BE AT LEAST ONE OF THE SAID SUBSTITUENTS (A), (B) AND (C) FOR EVERY NINE CARBON ATOMS IN THE SAID SIDE CHAINS AND BEING AT LEAST ONE CARBON ATOM REMOVED FROM THE CARBON ATOM OF THE SAID SIDE CHAIN WHICH IS LINKED TO THE SAID CATENARIAN CARBON.
Claim 2
Dependent Claim
226 words
A SHAPED STRUCTURE OF A GRAFT COPOLYMER OF FIBERFORMING MOLECULAR WEIGHT COMPRISING (1) A HIGH MOLECULAR WEIGHT, SYNTHETIC LINER POLYMER FROM THE CLASS CONSISTING OF A POLYAMIDE, A POLYURETHANE, A POLYUREA AND A POLYSULFONAMIDE WHEREIN THE AMIDO GROUPS OF THE RECURRING INERUNIT LINKAGES ARE AN INTEGRAL PART OF THE POLYMER CHAIN AND (2) GRAFT COPOLYMERIZED THERETO, FROM AT LEAST 4 TO ABOUT 200 WEIGHT PERCENTAGE, BASED ON THE WEIGHT OF THE ORIGINAL LINEAR POLYMER, OF SUBSTANTIALLY LINEAR HYDROCARBON SIDE CHAINS, EACH SIDE CHAIN BEING ATTACHED BY A SINGLE CARVON-TO-CARBON BOND TO A CATENARIAN CARBON OF THE SAID LINEAR POLYMER, EACH SAID SIDE CHAIN BEARING AS SUBSTITUENTS FOR HYDROGEN RADICALS FROM THE CLASS CONSISTING OF (A) AMIDO RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH CARBONYL CARBON, (B) AMIDO RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH AMIDE NITROGEN, AND (C) LACTAM RADICALS BONDED TO THE SAID SIDE CHAIN THROUGH LACTAM NITROGEN, WITH THE PROVISO THAT ANY OF THE SAID SUBSTITUENTS (A), (B) AND (C) HAS A MIXIMUM CARBON ATOM CONTENT OF 6 AND WITH THE FURTHER PROVISO THAT THERE BE AT LEAST ONE OF THE SAID SUBSTITUENTS (A), (B) AND (C) FOR EVERY NINE CARBON ATOMS IN THE SAID SIDE CHAINS AND BEING AT LEAST ONE CARBON ATOM REMOVED FROM THE CARBON ATOM OF THE SAID SIDE CHAIN WHICH IS LINKED TO THE SAID CATENARIAN CARBON.
Claim 3
Dependent Claim
110 words
A PROCESS FOR PRODUCING THE PRODUCT OF CLAIM 1 WHICH COMPRISES INTIMATELY CONTACTING (A) A SHAPED STRUCTURE OF HIGH MOLECULAR WEIGHT SYNTHETIC LINEAR POLYMER FREE OF FREE-RADICAL INITIATING PEROXY SITES FROM THE CLASS CONSISTING OF A POLYAMIDE, A POLYURETHANE, A POLYUREA AND A POLYSULFONAMIDE WHEREIN THE AMIDO GROUPS OF THE RECURRING INTERUNIT LINKAGES ARE AN INTEGRAL PART OF THE POLYMER CHAIN AND (B) A FLUID AMIDE CONTAINING LESS THAN 9 CARBON ATOMS AND A SINGLE REACTIVE ALIPHATIC UNSATURATED BOND UNTIL THE SAID FLUID HAS PENETRATED AT LEAST ABOUT 5% OF THE CROSS-SECTIONAL AREA OF THE SAID SHAPED STRUCTURE, AND HEATING THE RESULTING MASS IN THE PRESENCE OF A FREE-RADICAL INITITOR.
