Abstract: A METHOD FOR PRODUCING A POLYPROPYLENE COMPOSITION HAVING A MELT ELASTICITY (SWELL) VALUE BETWEEN 1.5 AND 3.0 COMPRISES CONTACTING THE POLYPROPYLENE WITH OXYGEN, HEATING THE POLYPROPYLENE IN THE FEED-END OF AN EXTRUDERREACTOR AT TEMPERATURE BETWEEN 600* AND 1,000*F. AND THEN COOLING THE POLYPROPYLENE TO A MELT TEMPERATURE NOT IN EXCESS OF 600*F. A POLYPROPYLENE COMPOSITION HAVING A MELT ELASTICITY (SWELL) OF LESS THAN 3.0 HAS A MOLECULAR WEIGHT DISTRIBUTION WHICH IS VERY NARROW AS COMPARED TO COMMERICAL POLYPROPYLENE COMPOSITIONS.

Abstract: A CATALYST IS PREPARED BY REACTING ALKYL ALUMINUM DIHALIDE IN THE ABSENCE OF A HYDROCARBON SOLVENT, WITH A COBALT SALT TO FORM A BLUE LIQUID COMPLEX. THE CATALYST SO FORMED MAY BE USED TO PREPARE HIGHLY UNSATURATED POLYMERS AND COPOLYMERS OF CATIONICALLY POLYMERIZABLE MONOMERS. THE POLYMERS OF THIS INVENTION ARE RUBBERY HIGH MOLECULAR WEIGHT MATERIALS. THE PREFERRED MONOMERS ARE ISOBUTYLENE AND ISOPRENE. THE PREFERRED ALKYL ALUNIMUM HALIDE IS ALUMINUM ETHYL DIHALIDE AND THE PREFERRED COBALT SALTS ARE COCL2 COBALT BROMIDE AND COBALT ACETONYL ACETONATE.

Abstract: THE VISCOSITY AND SHEAR MODULUS OF VISCOELASTIC MATERIALS ARE DETERMINED BY MEASURING THE PRESSURE DROP ACROSS TWO CAPILLARY TUBES IN SERIES CONNECTION. THE SECOND CAPILLARY TUBE IS ELONGATED, AND BOTH TUBES ARE OF UNIFORM DIAMETER THROUGHOUT THEIR LENGTHS. THE MATERIAL IS FORCED THROUGH THE TUBES BY A GEAR PUMP AT A KNOWN CONSTANT RATE OF SHEAR INDEPENDENT OF THE VISCOSITY OF THE VISCOELASTIC MATERIAL BEING TESTED.

Abstract: MINERAL HYDROCARBON FEEDSTOCKS WHICH ARE SUBJECTED TO ELEVATED TEMPERATURES OF THE ORDER OF 200* TO 1300*F. AND WHICH HAVE A TENDENCY TO FORM DEPOSITS BY REASON OF SUCH HEATING HAVE ADDED THERETO MINOR AMOUNTS, OF THE ORDER OF 1 TO 400 PARTS PER MILLION BY WEIGHT, AS A PRETREATMENT OF A CONDENSATION PRODUCT OF A LONG CHAIN ALKYL OR ALKENYL MONOCARBOXYLIC ACID, DICARBOXYLIC ACID OR ANHYDRIDE THEREOF, HAVING A NUMBER AVERAGE MOLECULAR WEIGHT BETWEEN ABOUT 600 AND ABOUT 5000, AND AT LEAST ONE POLYALKYLENE POLYAMINE AND AN ADDITION SMALL AMOUNT OF A PHOSPHOROUS ACID OR A MONO--, DI- OR TRIORGANIC PHOSPHITE ESTER HAVING THE FORMULA:

R1-O-P(-O-R2)-O-R3

WHEREIN R1 IS HYDROGEN OR A HYDROCARBON RADICAL SUCH AS ALKYL, ARYL, ALKARYL, CYCLO ALKYL, ALKENYL, ARALKYL OR SIMPLE CHLORINATED SUBSTITUENTS THEREOF AND R2 AND R3 ARE HYDROGEN OR ARE SELECTED FROM THE SAME GROUP AS SHOWN FOR R1. BEST ANTIFOULANT RESULTS ARE OBTAINED WHERE THE CONDENSATION PRODUCT AND THE PHOSPHOROUS COMPOUND AS ADMIXTURES OR AS THE PREREACTED COMPOUND OF THESE TWO TYPES OF ADDITIVES ARE ADDED TO THOSE FEEDSTOCKS WHICH CONTAIN OXIDIZED HYDROCARBONS AND/OR UNSATURATED HYDROCARBONS.

Abstract: Thermoplastic containers having a single open end of improved vertical strength properties are secured by employing a series of interconnected, vertically disposed supporting columns as part of the wall of the container. Preferably, the supporting columns extend laterally, outwardly from the noncolumn containing surface of the container sidewall. Each of the columns comprises two substantially identical isosceles trapezoids, each having a base and a side opposite therefrom of from 25 to 75 percent of the length of the base, and an elongated rectangular member of a length substantially equal to the length of the base of the trapezoids. The rectangular member is positioned between and connected to the bases of the trapezoids. Successive columns are interconnected along the side opposite the base of the trapezoids.
