    摘要： Age resistant resin which comprises a composition selected from (A) a composition having a softening point in the range of 0.degree. C to about 140.degree. C comprising units derived from selected aliphatic diolefins and aliphatic monoolefins, which can be modified with units derived from dicyclopentadiene, and certain vinyl aromatic compounds, and selected phenol or amine type compounds and (B) a composition having a softening point in the range of about 60.degree. C to about 110.degree. C comprising units derived from monoolefins and vinyl aromatic compounds, which can be modified with aliphatic diolefins, and selected phenol and amine type compounds. Such age resistant resins have particular utility when admixed with various rubbery materials and thermoplastics to create pressure sensitive adhesives and hot melt adhesives.

    摘要： This invention is directed to dispersions containing stabilizing amounts of certain substantially linear interpolymeric interfacially spreading polyelectrolytes composed of a mixture of nonionic hydrophobic units and ionic hydrophilic units where the nonionic units are randomly distributed in the backbone of the polyelectrolyte and where the polyelectrolyte is adsorbed at the surface of the disperse phase of the dispersion in a substantially flat configuration. The polyelectrolytes are further characterized by having an adsorption constant equal to or greater than 1 at the point where the surface of the disperse phase is saturated with the polyelectrolyte, the absorption constant being determined as the amount of polyelectrolyte in the disperse phase divided by the amount of polyelectrolyte in the continuous phase. These stabilized dispersions are particularly useful as coating compositions and for use in the preparation of microspheres and seed latexes.

    摘要： N-3-Aminoalkyl propionamides with an ether substituent on the beta carbon atom are prepared by the reaction of analogous N-3-oxohydrocarbon-substituted amides with an amine in the presence of a reducing agent, preferably hydrogen and a hydrogenation catalyst. The resulting compounds can be converted to acrylamides by pyrolysis in the presence of a strong base. The latter compounds may also be prepared by the reaction of a .beta.,.gamma.-unsaturated amine with an acrylonitrile in the presence of sulfuric acid. They are useful for improving dyeability of fiber-forming polymers and may be polymerized to form compositions which are useful in paper manufacture and (in their quaternized form) are excellent flocculants.
