Abstract: In accordance with the present invention, it has been found that liquid stabilizer compositions for vinyl halide polymers that are compatible with and form stable mixtures with epoxidized glycerides can be prepared by a process which comprises heating a non-homogeneous mixture comprising (A) at least one epoxidized glyceride, (B) at least one hydrocarbon-soluble, (B-1) basic alkali or alkaline earth metal salt of an alkyl phenol, or (B-2) basic alkali or alkaline earth metal salt of a monocarboxylic acid, and (C) a hydrocarbon diluent, at an elevated temperature until the mixture is homogeneous. Generally, the metal salts are alkaline earth metal salts such as calcium and barium, and the basic alkaline earth metal salt utilized in this system is a salt of an aliphatic monocarboxylic acid prepared in the presence of a phenol promoter. The invention also relates to stabilizer compositions thus prepared and to stabilizer compositions optionally containing (D) substantially neutral polyvalent metal salts of carboxylic acids and/or (E) organic phosphites. Vinyl halide polymer compositions comprising a vinyl halide polymer and a stabilizing amount of the homogeneous stabilizer compositions of the invention also are described and claimed.

Abstract: A machine for transforming zigzag wire to the slotted tubular form ready for use as a binding element comprises means for feeding a strip of zigzag wire longtitudinally, means for arresting the feed of each prong of the wire strip as it reaches a shaping station, means for clamping each prong at that station and means at the station for shaping each clamped prong. The shaping means comprises two or more forming tools mounted on rollers which are driven by drive shafts, at least one roller being angularly adjustable relative to its drive shaft. This allows the operation of the forming tools to be synchronised so that symmetrical shaping of the zigzag wire is achieved. The feed means are rotary and means are provided whereby the feed of each prong is arrested for at least one eighth of each revolution of the rotary feed means The shaping of the zigzag strip is facilitated and improved since the strip is held stationary for a relatively long period of time.
