Abstract: Disclosed is a process to produce an improved formulated vinylidene chloride polymer comprising a solid inorganic additive and producing improved vinylidene chloride polymer film products. The process includes adding the inorganic solid additive (such as magnesium hydroxide and/or other inorganic acid scavenger) in a dispersion of a liquid, such as a liquid plasticizer or stabilizer to improve distribution through the polymer and reduction of relatively large sized particles or agglomerates in the polymer and film.

Abstract: A process for recycling and reblending dry, difficult to hydrate polymer fines into a water-swellable fluid absorbent polymer gel is disclosed. The process requires feeding the dry polymer fines into a first mixing zone where they are subjected to spraying with water that at least partially hydrates the fines and mixing, substantially simultaneously with the water contact, at high shear such at the fines are substantial completely hydrated without agglomeration. The hydrated fines are then transported from the first zone into a second mixing zone where blending of the hydrated fines with fresh polymer gel occurs at medium shear such that a substantially uniformly blended product results. The resulting process successfully re-introduces fines into the main product stream wherein the resulting product has high aqueous fluid absorbent capacity and good particulate mechanical integrity.
