RESINS
TB&C has created a new series of low molecular weight styrene-maleic anhydride copolymers offering these extremely interesting chemical and physical properties: Low molecular weight (approx. 1600) makes for broad versatility of end-use applications. Polyanhydride structure permits infinite variety of chemical derivatives—easily reacted with ammonia and alcohols and crosslinked with glycols. Alkali solubility allows high solids solutions (up to 50%) at workable viscosities (5000 cps). Surface active propertiesfunction as wetting agents and protective colloids, yet act as film formers in coatings applications. SMA resins have shown promise as modifiers of commercially available latexes in paints; as suspending agents in emulsion polymerization; as pigment dispersants; as alkali soluble components in emulsion floor polishes; as shellac replacements; in water soluble surface coatings, adhesives, paper coatings, textile sizes and aerosol hair sprays. Samples and complete data on SMA resins available on letterhead request. THE SMA 1000A RESIN MOLECULE HAS AN AVERAGE OF ONLY 8 STYRENE-MALEIC ANHYDRIDE GROUPS.
