Can you pass this acrylic quiz? If you're working on polymers for plastic sheets, molding powders, coatings, adhesives, latex paints, elastomers, binders, water-soluble thickeners, ion exchange resins, or emulsions for paper, textile, and leather finishing, you may solve many of your problems by copolymerizing your monomer with one or more of the many acrylic monomers supplied by Rohm & Haas. The benefits illustrated above are only a few you can derive by copolymerizing with acrylics. Others include improved compatibility with other resins, oil solubrlity, better adhesion properties for binders and coating resins, faster polymerization rate and greater copolymer yield, solubility in alkalis, and increased toughness, hardness, softening temperature, and abrasion resistance. Get more information on these polymer improvements by writing to Dept. SP-8 for the Acrylic Library, a collection of 19 booklets and technical bulletins on acrylic monomers. Monomer samples are also available.
ANSWERS \1\ CopoJymerize with butyl acrylate or 2-ethylhexyl acrylate. [ 2 j Copolymerize with dimethylaminoethyl toethacrylate or t-butylaminoethyl methacrylate. [ 3 j Add carboxyl groups to your polymer, by copolymerizing with acrylic acid or methacrylic acid. [4"] Copolymerize with methyl methacrylate.
