| titleOfInvention | Graft polymerization of vinyl monomers onto chrome-tanned hides and skins |
| abstract | 1. A PROCESS FOR GRAFT POLYMERIZING A VINYL MONOMER ONTO A CHROME-TANNED HIDE, COMPRISING THE FOLLOWING STEPS; 8A) PLACING IN A CONTAINER A CHROME-TANNED HIDE IN WET, DRAINED CONDITION AND A SOLUTION CONTAINING WATER, A SURFACTANT-EMULSIFIER, AND A REDOX POLYMERIZATION INITIATOR SYSTEM CONSISTING OF POTASSIUM PERSULFATE AND SODIUM BISULFITE; (B) ADDING TO THE MIXTURE OF STEP (A) SUFFICIENT DRY ICE TO DISPLACE ALL THE AIR IN THE CONTAINER WITH CO2; (C) SEALING THE CONTAINER AND MIXING THE CONTENTS FOR ABOUT 30 MINUTES; (D) ADDING TO THE MIXED CONTENTS DESCRIBED IN STEP (C) A MONOMER SELECTED FROM THE GROUP CONSISTING OF ACRYLIC ACID, BUTYL ACRYLATE, ETHYL ACRYLATE, ETHYLHEXYL ACRYLATE, METHYL METHACRYLATE, BUTYL METHACRYLATE, ACRYLONITRILE STYRENE, METHACRYLIC ACID AND MIXTURES THEREOF; (E) ADDING TO THE MIXTURE DESCRIBED IN STEP (D) SUFFICIENT DRY ICE TO AGAIN DISPLACE THE AIR IN THE CONTAINER WITH CO2; (F) RESEALING THE CONTAINER; AND (G) MIXING THE CONTENTS OF THE CONTAINER AS DESCRIBED IN STEP (E) UNTIL POLYMERIZATION OF THE MONOMER IS COMPLETE AND UP TO 30% OF THE FORMED POLYMER IS GRAFT COPOLYMERIZED TO THE CHROME-TANNED HIDE. |
