    Abstract: Dialkanesulfonyl peroxide (RSO2-0-0-02SR) is prepared in a continuous process by electrolyzing the corresponding alkanesulfonic acid at an elevated temperature (to keep the peroxide product in solution ) in a continmuous-flow electrolysis cell, removing the solution from the electrolytic cell, cooling the solution to precipitate the peroxide product, and recycling the supernatant alkanesulfonic acid back to the cell.

    Abstract: Polymer bound antioxidants in which the antioxidant stabilizer groups are chemically bound to polymers or copolymers by an acylaminoimide or diacylhydrazide function are prepared by reacting hydrazido substituted antioxidants with some or all of the anhydride groups of anhydride containing polymers or copolymers to form a polymer with recurring units selected from the formulas or both wherein the units occur, e.g., in the polymer backbone, x is 0 or 1, R and R are, e.g., hydrogen and G is, e.g., wherein R is t-alkyl of 4-8 carbons, R is, e.g., hydrogen and X is, e.g., -N(R)-C(=O)-(CH2)b- wherein R is e.g., hydrogen and b is 0, 1 or 2. The concentration of the stabilizers bound to the polymer may be readily varied depending upon the particular end-use of said polymer. Polymer with high concentrations of bound antioxidants can be used as masterbatches to stabilize other polymer systems.

    Abstract: This invention relates to a method for manufacturing polyesters, in particular, to using a lithium titanyl oxalate as the catalyst for such reaction to provide fast reactions with excellent color properties for the resulting polyester. The present invention provides an improved method of producing polyester by the polycondensation of polyester forming reactants wherein the improvement comprises utilizing, as the polycondensation catalyst, lithium titanyl oxalate. The improved process produces a polyester of improved color verses other titanyl oxalate catalysts and a novel polyester without the presence of antimony.
