Abstract:
The present invention comprises novel single-functional and mixtures of multi-functional oligomeric performance additive compounds having one or more components of Structure A (The definitions of R, Z1, Z2, Z3, A1, A2, A3 and y are given in the Summary Section), their uses and polymeric compounds and compositions containing them which have enhanced oxidative stabilities, enhanced ultraviolet (UV) and light stabilities and/or enhanced flame retardance. An example is the bis sulfonic acid bispotassium salt reaction product from an oligomeric caprolactone diol (TONE® 260), 2-sulfobenzoic acid anhydride and potassium carbonate, and use of this product, at levels up to about 3.0%, in a general purpose bisphenol A polycarbonate resin, to enhance the fire resistance or flame retardance of the polycarbonate resin.
Abstract:
A novel peroxide composition of Structure A , and use of the novel oxalic acid peroxide composition of Structure A as an initiator; a) for curing of unsaturated polyester resins, b) for polymerizing ethylenically unsaturated monomers, c) for crosslinking of polyolefins, d) for curing of elastomers, e) for modifying polyolefins, f) for grafting of vinyl monomers onto polymer backbones and g) for compatibilizing blends of two or more incompatible polymers are disclosed.
Abstract:
A masterbatch composition is provided, comprising about 0.001% to about 70% by weight of an organic peroxide homogeneously dispersed in a polycaprolactone carrier. The peroxide master-batches are safer and easier to store, ship, handle and use than the peroxides from which they are made.

Abstract:
Novel functionalized peroxides which may be used as crosslinking, grafting and curing agents, initiators for polymerization reactions and as monomers for condensation polymerizations to form peroxy-containing polymers, which in turn can be used to prepare block and graft copolymers, have the following Formula I :
R¹, R², R³, R⁴, R⁵, R⁶, R⁷, X, Y¹, Y², Y³, Z¹, Z², x, y and z are as defined in the Summary of the Invention. The compounds of Formula I may be prepared by reacting hydroxy-containing tertiary hydroperoxides with diacid halides, phosgene, dichloroformates, diisocyanates, anhydrides and lactones to form the functionalized peroxides. These reaction products may be further reacted, if desired, with dialcohols, diamines, aminoalcohols, epoxides, epoxy alcohols, epoxy amines, diacid halides, dichloroformates and diisocyanates to form additional functionalized peroxides.
