| titleOfInvention | PROCEDURE FOR THE PREPARATION OF POLYBUTADIENE 1, 4-CIS BY CATALYTIC POLYMERIZATION OF BUTADIENE MONOMER, IN THE ABSENCE OR SUBSTANTIALLY IN THE ABSENCE OF SOLVENTS OR THINNERS. |
| abstract | PREPARATION OF POLYBUTYDENE 1, 4-CIS BY CATALYTIC POLYMERIZATION OF BUTADIENE MONOMER, IN THE ABSENCE OF SOLVENTS, WHICH INCLUDES THE STAGES: A) TO CONTACT IN A VEHICLE OF INTEX HYDROCARBON, I) NEODIUM OXIDE HYDROXYLIC OR CARBOXYLIC GROUPS CHOSEN BETWEEN NAFTENIC ACIDS AND WATER, III) A HALOGENATED COMPOUND CHOSEN BETWEEN ALKYL HALOGENUROS OF ALQUILY, SEQUENTIAL ALKYRIDE, AND HALOGENURIUM COMPOSITIONS I) AND II) SUCH AS TO RESPECT A RELATIONSHIP BETWEEN THE HYDROXYLIC GROUPS (UNDERSTANDING THOSE OF WATER) AND / OR CARBOXYLICS AND NEODYMIUM ATOMS FROM 2/1 TO 100/1; AND MAINTAINING A CONTACT OF THE MENTIONED COMPONENTS TO OBTAIN A CATALYTIC MIX IN WHICH THE ATOMIC ALUMINUM / NEODYMIUM RELATIONSHIPS FROM 20/1 TO 200/1 AND HALOGEN / NEODYMIUM FROM 0, 2/1 TO 3/1; B) CONTINUOUS FEEDING OF THE CATALYTIC MIXTURE AND THE LIQUID BUTADIENE MONOMER, BY AN EXTREMITY OF A LONG POLYMERIZATION REACTOR, IN WHICH THE MIXTURE RUNS WITH A PISTON IMPULSE, KEEPING A TEMPERATURE OF ENTRY AND DELIVERY CONTROLLED PARTIAL EVAPORATION OF THE BUTADIEDO MONOMER IN LIQUID PHASE, UP TO OBTAINING A MIXTURE WITH A POLYMER CONTENT OF 25 TO 70% BY WEIGHT, WHICH IS DISCHARGED BY THE OTHER EXTREMITY OF THE REACTOR; SEPARATION AND RECOVERY OF POLYBUTADIENE 1, 4-CIS FROM THE DOWNLOADED MIXTURE. |
