  • Method of reducing impurities in aqueous acrylic monomer solutions
    Patent number: 5208370
    Abstract: The present invention provides a method of reducing the levels of protoanemonin present in aqueous monomer solutions by adding an effective amount of one or more para-phenylenediamines having the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are the same or different radical selected from hydrogen, methyl, ethyl, n-propyl, iso-propyl, phenyl or methoxyphenyl with the proviso that at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is hydrogen; R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are the same or different radical selected from hydrogen, methyl, ethyl, n-propyl, iso-propyl, methoxy or ethoxy with the proviso that at least one of R.sub.5, R.sub.6, R.sub.7 and R.sub.8 is hydrogen; and salts thereof.
    Type: Grant

  • Urethane elastomer with active hydrogen containing monoethylenically unsaturated monomer
    Patent number: RE29772
    Abstract: A urethane elastomeric impact modifier is provided for 15 rigid thermoplastic polymers. Polyester and polyether urethane elastomers are grafted to the acrylic polymers. Preferred is a polyester, diisocyanate and glycol urethane elastomer terminated with a functional monomer capable of ethylenic polymerization grafting with the acrylic polymer. The modified polymers offer an improved balance of physical properties including higher impact strength, clarity, and weather resistance.
