Utilization of cellulose acetate butyrate and aryl sulfonamide-formaldehyde resin containing dispersant

A method of utilizing the cellulose acetate butyrate containing dispersant composition to disperse a resin additive into a given resin system comprising the steps of:

• a. providing a given weight of resin additive dispersant composition consisting essentially of cellulose acetate butyrate, aryl sulfonamide-formaldehyde resin, and a non-ionic surfactant, said surfactant comprising up to 1%, by weight, of said composition, the remainder of said composition comprising:
• i. said cellulose acetate butyrate, having a butyrate content, in weight percent of from 17 to 65 and a falling ball viscosity, as measured by ASTM Method D-1343-54T in a solution of formula A of ASTM Method D-871-54T of from 1/2 to 40 seconds, and
• ii. said aryl sulfonamide-formaldehyde resin in a weight ratio range (ratios of (i) to (ii)) from 80:20 to 30:70;
• b. mixing said resin additive into resin additive dispersant composition in a ratio of from 2/3 to 9 times said given weight of said resin additive dispersant composition, to produce a dispersed resin additive composition;
• and
• c. dispersing the dispersed resin additive composition in a given resin system selected from the group consisting of polyvinylchloride, polyvinylacetate, polyvinylchloride copolymer, polyvinylacetate copolymer, thermoplastic rubber, polyurethanes, polyolefins, solution grades of polyamids, and thermoplastic ketone soluble acrylics.
