摘要： POLY(VINYL CHLORIDE) HOMOPOLYMER COMPOSITIES HAVING IMPROVED RHEOLOGICAL PROPERTIES ARE READILY PREPARED BY ADDING PLASTICIZERS AND STABILIZERS TO AQUEOUS DISPERSIONS OF THE POLY(VINYL CHLORIDE) HOMOPOLYMER PARTICLES AND FREEZE-DRYING THE DISPERSIONS. OTHER ADDITIVES SUCH AS FINELY DIVIDED PIGMENTS MAONS. OTHER ADDITIVES SUCH AS FINELY DIVIDED PIGMENTS MAY BE INCORPORATED BY MIXING PRIOR TO FREEZE-DRYING TO PRODUCE PREBLENDED BINDER SYSTEMS. THE INVENTION IS CONCERNED WITH HOMOPOLYMERS OF POLY(VINYL CHLORIDE) RESIN WHICH ARE PREPARED BY EITHER SUSPENSION OR BULK POLYMERIZATION TECHNIQUES.

摘要： TO PRODUCE A HIGHLY CRYSTALLINE POLYMER SUBSTANTIALLY FREE OF IMPURITIES.

PROCESSES FOR POLYMERIZING ALPHA OLEFINIC HYDROCARBONS COMPRISING POLYMERIZING AN ALPHA OLEFIN WITH A SOLID STEREOSPECIFIC CATALYST IN THE PRESENCE OF A DILUENT WHICH IS A SOLVENT FOR THE POLY-ALPHA-OLEFIN AT THE REACTION TEMPERATURE TO PRODUCE A POLYMER SOLUTION CONTAINING CATALYST RESIDUES. THE POLYMER SOLUTION IS FILTERED TO REMOVE CATALYST REDISDUES. THE FILTERED SOLUTION IS CONTACTED WITH ALUMINA AND CONCENTRATED TO FORM A SOLID POLYMER CONCENTRATE CONTAINING RESIDUAL SOLVENT. PELLETS ARE FORMED OF THE POLYMER CONCENTRATE AND THE PELLETS EXTRACTED WITH A SOLVENT FOR AMORPHOUS LOW MOLECULAR WEIGHT POLYMER

摘要： IN A PROCESS FOR FORMING SULFURIZED POLYBUTENES FOR USE IN METAL WORKING OILS INCLUDING REACTING MOLTEN SULFUR WITH LOW MOLECULAR WEIGHT POLYBUTENES, STRIPPING TO REMOVE LIGHT UNDERIRABLE COMPONENTS SUCH AS HYDROGEN SULFIDE, VARIOUS MERCAPTANS AND UNREACTED POLYBUTENES, REMOVING ENTRAINED SULFUR AND COOLING TO AMBIENT CONDITIONS, THE IMPROVEMENT WHICH COMPRISES ENHANCING THE RETENTION OF CHEMICALLY COMBINED SULFUR IN SUCH POLYBUTENES BY MAINTAINING THE PH IN THE RANGE OF ABOUT 2.0 TO 5.5 FOR A PERIOD OF TIME SUFFICIENT TO SUBSTANTIALLY STABILIZE THE CHEMICALLY COMBINED SULFUR CONTENT OF THE SULFURIZED POLYBUTENES. SUITABLY, THE PH IS MAINTAINED WITHIN THE RANGE SET FORTH FROM AFTER THE STRIPPING STEP UNTIL AT LEAST THE AMBIENT CONDITIONS ARE REACHED. CONTINUED MAINTENANCE OF THE PH DURING STORAGE IS ALSO DESIRABLE.

摘要： THERE IS PROVIDED A PROCESS FOR ISOLATING ORGANIC COMPOUNDS, INCLUDING POLYMERS OR COPOLYMERS FROM AN ORGANIC SOLUTIN THEREOF. THE ORGANIC SOLUTION IS INTRODUCED INTO A VORTEX CHAMBER AT A POINT ADJACENT TO THE PERIPHERY OF THE CYLINDRICAL SIDE WALL OF THE VORTEX CHAMBER WHEREIN IT IS BROUGHT IN CONTACT WITH A VORTEX FLOW OF WATER OF A TEMPERATURE NEAR THE BOILING POINT OF THE SOLVENT UNDER THE PREVAILING PRESSURE. THE ORGANIC SOLUTION OF WHICH THE SPECIFIC GRAVITY HAS TO BE LOWER THAN THAT OF WATER IS DISPERSED IN THE WATER PHASE AT A POINT AWAY FROM THE INTERFACE BETWEEN THE LIQUID AND THE HOLLOW CORE IN THE VORTEX FLOW. TO INCREASE THE SPECIFIC GRAVITY, DISSOLVED SALTS OR SUSPENDED SUBSTANCES MAY BE ADDED TO THE WATER PHASE. THE ORGANIC SOLUTION MAY BE ADDED TO THE WATER IMMEDIATELY BEFORE IT ENTERS THE VORTEX FLOW OR MAY BE SUPPLIED THROUGH AN AXIALLY OR RADIALLY DISPOSED FEED PIPE TO THE WATER PHASE OF THE VORTEX FLOW.
