STABILIZED RHEOLOGY MODIFIER EMULSIONS

The present technology discloses emulsion polymers prepared in the presence of a stabilizer system comprising digested starch, poly(vinyl alcohol) and an acid component selected from a saturated C.sub.2 to C.sub.50 mono- or diacid, an unsaturated C.sub.10 to C.sub.50 mono- or diacid, and mixtures thereof. In one aspect, the polymers are utilized as alkali-swellable emulsion (ASE) and hydrophobically modified alkali-swellable emulsion (HASE) thickeners in sulfate and sulfate-free surfactant systems to achieve good rheology and clarity attributes.

A PROCESS OF MANUFACTURING DIPPED LATEX PRODUCTS WITHOUT USING ANIMAL DERIVATIVES AND PRODUCTS THEREOF
20170081484 · 2017-03-23 ·

The present disclosure provides for a process for manufacturing of dipped latex products without using any animal derived ingredients and dipped latex products produced by said process. The disclosed process successfully over comes drawbacks of drop in product yield (due to coagulum formation) and burst pressures caused by absence-of casein in latex formulation. Therefore, the dipped latex products so produced through the process have final composition similar to that of any other dipped latex products with casein except for absence of casein and having 0.8 phr of Sulphur as against 0.6 phr of Sulphur in routine manufacturing. The products also exhibit physical properties similar to that of any other dipped latex products with casein, such as burst pressure and burst volume.
