  • Patent number: 5674951
    Abstract: Coating compositions are disclosed which use a polyoxetane polymer having CH.sub.2 --O---CH.sub.2 --R.sub.f side chains where R.sub.f is a highly fluorinated alkyl or polyether. The coating compositions use polyisocyanates to create isocyanate terminated polymers from the poly(oxetanes) and from various polyols from alkylene oxides or polyester polyols. These can be reacted together to form block copolymer structures or can be linked together when the coating is crosslinked. A preferred method is to use blocked isocyanate groups. Another preferred embodiment is to use the composition as a abrasion resistant coating for glass run channels.

  • Patent number: 5670574
    Abstract: Resin-salt plastic or polymeric reaction products are produced by reacting a resin, such as polyvinyl alcohol, with a metal salt, such as sodium chloride, in a reaction medium under agitation and conditions in which the resin does not precipitate or kick out of the reaction medium, but is solubilized in the reaction medium and reacts with the salt. The amount of salt present is at least 2.3 weight percent of the resin and is preferably added to the reaction medium in a single charge. The reaction product is separated from a mother liquor and preferably washed to remove unreacted materials and contaminants. The resin-salt reaction product, the mother liquor, and the wash liquid each have utility in the manufacture of commercially useful products.
