New R & D starting point! Now available for the firsttime in semi-commercial quantities, these two corn starch frac tions create unlimited opportunities in product improvement...new product development The molecular structure, behavior and versatility of two new natural polymers—NAPOL L and NAPOL B—provide
rich food for creative thought for research chemists. Opening up a wide range of applications in many fields, NAPOL L (linear) and NAPOL Β (branched) are the end re
sults of a unique process, developed by Staley's, which separates the amylose and amylopectin fractions of regular dent corn. NAPOL L—linear stereospecific polymer of anhydroglucose units. Forms high strength gels. Oriented films are high strength, edible, transparent, abrasion resistant.
Three sites on each glucose unit available to form esters, ethers, acetals, amines. Substantive to cellulose. High reactivity with cross-linking agents. NAPOL B—branched, amorphous polymer of anhydroglucose units. High molecular weight. Cold water soluble. High reactivity with cross-linking agents. Solutions have relatively stable viscosity. Perhaps these two new products are just the stimuli needed to transform nascent ideas into reality. For samples and technical data, write: MARKET DEVELOPMENT DIVISION
