    Abstract: Stabilized poly-alpha-olefin compositions comprising polymer and up to 5 percent by weight thereof of stabilizing mixture of: A. A THIOESTER DERIVED FROM THIODIPROPIONIC ACID OR FROM BISBeta -HYDROXYETHYL SULFIDE (THIODIGLYCOL); B. A PHOSPHITE HAVING THE FORMULA:

    WHEREIN X is oxygen or sulfur and R, R'', R'''' are the same or different radicals selected from the group consisting of unsubstituted or hydroxy substituted alkyl, aryl and alkylaryl radicals; C. A PHENOLIC ANTIOXIDIZING AGENT; D. AN ORGANOTIN COMPOUND; E. A METALLIC SOAP, SELECTED FROM THE GROUP CONSISTING OF THE STEARATES OF Ca, Mg and the like; and optionally a basic nitrogen containing polymer. 2. Description of the Prior Art Various compounds are known to stabilize poly-alpha-olefins against the deleterious effects of heat and/or light and/or ageing. No one of these compounds, nor any mixture thereof known to me, has given the surprising degree of stabilization afforded by the particular combination of ingredients comprising the stabilizing mixture of the present invention.

    Abstract: PROCESS FOR THE PREPARATION OF ORGANOBORON COMPOUNDS OF THE GENERAL FORMULA BR3, WHEREIN R IS AN ALKYL, ARYL, CYCLOALKYL OR ARALKYL RADICAL, FOR USING IN CATALYSTS FOR THE POLYMERIZATION OF VINYL COMPOUNDS IN ORGANIC SYNTHESIS, ETC., BY REACTING THE COMPONENTS OF A GRIGNARD REAGENT OF THE GENERAL FORMULA R.MG.X, WHERE R IS THE AFOREMENTIONED RADICAL AND X IS A HALOGEN FROM THE GROUP OF CHLORINE, BROMINE AND IODINE, WITH A POLYBORATE BORON DERIVATIVE OF THE GENERAL FORMULA (R''O)3B.NB2O3 (WHERE R'' IS AN ALKYL RADICAL HAVING A STRAIGHT OR BRANCHED CHAIN CONTAINING FROM 2 TO 6 CARBON ATOMS, A PHENYL, AN ALKYL SUBSTITUTED-PHENYL OR PHENYL SUBSTITUTED ALKYL, AND N IS A NUMBER EQUAL TO OR UPWARDS OF 1, BUT PREFERABLY LESS THAN 2). THIS GRIGNARD REAGENT IS PREPARED FROM AN RX TYPE COMPOUND AND A SUSPENSION OF MAGNESIUM IN AN INERT ORGANIC HYDROCARBON SOLVENT CONTAINING ONLY CATALYTIC QUANTITIES OF AN ETHER SUCH THAT THE MOLAR RATIO OF ETHERS TO THE RX COMPOUND RANGES SUBSTANTIALLY FROM 0.01 TO 0.5. THE MAGNESIUM MAY BE ACTIVATED WITH SMALL QUANTITIES OF ETHYL IODIDE PRIOR TO ITS INCORPORATION IN THE SUSPENSION.

    Abstract: DESCRIBED IS A PROCESS FOR PREPARING 2-TRANS-4-TRANS SORBIC ACID FROM PURE METHYL 2-CIS-5,2-TRANS-5,3-TRANS-5, HEXADIENOATE OR FORM MIXTURES THEREOF. THE PROCESS IS CHARACTERIZED BY THE FOLLOWING STEPS: METHYL HEXADIENOATE IS DISSOLVED IN METHANOL, USING 0.5 TO 1 PART OF METHANOL PER 1 PART OF ESTER; SOLID SODIUM HYDROXIDE IS ADDED IN AMOUNT FROM 0.5 TO 3% BY WEIGHT IN RESPECT OF THE ESTER AND THE WHOLE IS AGITATED AT 20-40*C. FOR 60-120 MINUTES (STEP A); SODIUM HYDROXIDE IS ADDED IN STOICHIOMETRIC AMOUNT FOR THE SAPONIFICATION AND THE WHOLE IS HEATED TO 60-80*C. FOR 60-120 MINUTES UNDER STIRRING (STEP B); WATER IS ADDED IN AMOUNT FROM 0.5 TO 1.5 VOLUMES OF WATER PER VOLUME OF SOLUTION IN ORDER TO DISSOLVE THE SALTS, AND THE METHANOL IS DISTILLED (STEP C); THE SOLUTION IS ACIDIFIED TO PH OF 3.5 WITH 5-15% SULFURIC ACID (STEP D); AFTER FILTRATION AT BETWEEN 30 AND 40*C. (STEP E), THE FILTER CAKE IS WASHED WITH WATER AND WITH AQUEOUS METHANOL (STEP F) THUS OBTAINING 2-TRANS-4-TRANS SORBIC ACID, WITH A PURITY HIGHER THAN 99%.
