PROCEDURE FOR OBTAINING COMPOSITIONS BASED ON ETHYLENE POLYMERS. IT INCLUDES THE OPERATIONS OF FORMING A COMPOSITION THAT INCLUDES AT LEAST ONE ADHESIVE AGENT SELECTED AMONG LIQUID POLYBUTENE, POLYISOBUTENE AND ATACTIC POLYPROPYLENE, AND AT LEAST ONE CRYSTALLINE WAX THAT HAS ONE OR MORE 200 GRINDING POINTS OF MELT PROMPTED AND PROMPTED 200 GROSS POINTS. BETWEEN 250 AND 15,000; TO HEAT THE ADHESIVE AGENT TOGETHER WITH THE CRYSTAL WAX TO A TEMPERATURE CLOSE TO THE FUSION TEMPERATURE OF THE CRYSTAL WAX OR HIGHER THAN THE SAME, UNTIL THE ASSEMBLY, BY COOLING AT ROOM TEMPERATURE, TAKES THE FORM OF A GEL; AND TO COMBINE THE PRODUCT RESULTING FROM THE PREVIOUS STAGE WITH THE POLYMER OR COPOLYMER OF ETHYLENE. OF APPLICATION IN THE FORMATION OF ADHESIVE AND ESTIRABLE FILMS. |
