Progress Test on:
MAN.. - the broad-application monomer to improve plastics, elastomers, and coatings MAN . . . VISTRON® methacrylonitrile . . . is a commercially available vinyl nitrile monomer. MAN has the polarity that provides resistance to solvents, acids, and alkalies similar to acrylonitrile (AN). Yet, MAN is truly thermoplastic as a homopolymer or component in copolymers. QUIZ FOR YOUR POLYMER CHEMIST Can he form copolymers with: MAN and Butadiene to produce elastomers, plastomers, or plastics with ultra-high nitrile contents that remain processable? MAN and Styrene when he needs to match a refractive index from 1.52 (PMAN) to 1.59 (PS)? The Polymerization azeotrope is 50 mole percent (R.I. = 1.555). MAN and Alpha-Methyl Styrene to produce, by free radical initiation, high-HDT copolymers that are clear, colorless and sterilizable? MAN and Methyl Methacrylate to wed MAN's excellent physical properties and solvent resistance to the ultimate in weatherability?
PHYSICAL PROPERTIES OF " M A N "
MAN and Acrylonitrile to explore properties near the thermoplastic limits of AN content? Also, has he determined the property changes in acrylic fibers modified with MAN? What is your progress with copolymers of MAN? These are only a few of the areas that should be explored with MAN. Write for technical literature and a sample. Methacrylonitrile is available commercially in tank cars, tank trucks, and drums from Vistron Corporation, a subsidiary of The Standard Oil Company (Ohio). Address:
