  • Hydroxylamine modified lower acrylate ester latices
    Patent number: 5405898
    Abstract: The acrylate ester groups of lower acrylate ester latex polymers are converted to hydroxamic groups by the expediency of pH adjustment and using salt free hydroxylamine. Lower reaction temperatures are used. A high HLB surfactant is also used to help further stabilize the particles. The finished modified acrylate ester latex polymers are considered to be new compositions having a use in a variety of industrial applications such as settling agents in the treatment Bayer process liquors.

  • Class of polymeric adhesives for yankee dryer applications
    Patent number: 5374334
    Abstract: The invention provides a method for manufacturing tissue paper. According to the method, a yankee dryer adhesive composition is applied to a metal surface of a drying drum. The yankee dryer adhesive composition preferably includes from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 of at least one monomer selected from the group consisting of vinylformamide, vinyl acetate and vinyl alcohol. The yankee dryer adhesive composition is contacted with a continuous paper web. The continuous paper web is then dried. The dry continuous paper web is creped with a metal blade to form tissue paper.
