  • Patent number: 4717643
    Abstract: Disclosed are dry film solder mask compositions containing a binder material that is the reaction product of: (a) a polymerized mixture of polypropyleneglycol monomethacrylate, methacrylic acid and, preferably, specific acrylates and methacrylates; and (b) isocyanatoethyl methacrylate. The masks are equal or superior to current dry film masks in affording protection to circuit boards.

    Inventors: Bernard J. Scheve, Clement L. Brungardt
  • Patent number: 4452855
    Abstract: The adhesion of fibrous polymeric aromatic amide reinforcing material to rubber stock is improved by treating the fibrous material with an aliphatic sulfonylazide having the general formula R(Cl).sub.x (SO.sub.2 N.sub.3).sub.y, where R is an aliphatic or cycloaliphatic hydrocarbon radical containing at least 5 carbon atoms, y is from about 1 to about 4 and x is from 0 up to about 2y; heating the treated fibrous material at a temperature and for a period of time sufficient to decompose substantially all the sulfonylazide groups; then coating the resulting material with an adhesive; and finally, embedding the coated material into rubber stock which is then vulcanized.
    Type: Grant

    Inventors: Gregory I. Brodsky, Bernard J. Scheve
  • Patent number: 4420611
    Abstract: The molecular weight of irradiated carboxymethyl cellulose can be stabilized by heat treatment of irradiated carboxymethyl cellulose at a temperature from about 50.degree. C. to about 150.degree. C., preferably from about 70.degree. C. to about 90.degree. C. Equal amounts of such stabilized carboxymethyl cellulose have essentially the same viscosity regardless of the time that has passed from irradiation until a solution is made.
    Type: Grant

  • Patent number: 4277593
    Abstract: Novel polymers are disclosed which are based on an ethylenically unsaturated monomer containing at least one azide group and another ethylenically unsaturated silane monomer. These materials are useful as coupling agents for thermoformable polymers such as polyolefins and inorganic fillers. Optionally the polymers can contain other ethylenically unsaturated monomers as spacers or extenders for the more expensive azide or silane monomers.
