  A method of preparing a polychloroprene-base adhesive characterized by excellent shear strength which comprises the steps of preparing a first solution by dissolving unmilled polychloroprene in from 300 to 500 percent by weight of an organic solvent for polychloroprene based upon the weight of said polychloroprene,preparing a second solution by dissolving an oil-soluble,gold processing plant,heat-advancing phenol-formaldehyde resin, with stirring, in an organic solvent for polychloroprene which is compatible with said first solution, the amount of said phenol-formaldehyde resin being from 30 to parts by weight per 100 parts by weight of said polychloroprene in said first solution,adding to said second solution from 10 to 40 parts by weight of an alkaline earth metal oxide per 100 parts by weight of said polychloroprene in said first solution to form a slurry of said metal oxide having a 7 8 solids content of from 50 to 60 percent by weightof 2.
  
  A polychloroprene-base adhesive having high shear solids, strength produced by the process of claim 1. grinding said slurry to reduce the fineness of said alkaline earth metal oxide to a reading of 5 to 8 on References Cited m the file of thls Patent 21 Hegrnan grind gage and provide stability against 5 NITED STATES PATENTS settling, and 2,459,739 Groten et a1 Jan. 18,silica grinding machine 1949 mixing said first and second solutlons, With simple ag1ta- 2 4 1 379 Ross Sept 13 1949 tion, to provide an adhesive composition having 21 2 10 910 Thomson Sept 1 1952 total solids content of from about 10 to about 65 2 91 442 Gerrard et 1 22, 1959 Percent 10 2,963,387 Herr etal Dec. 6, 1960
  
  This invention relates to the discovery that a combination of at least one herbicidal s-triazine with EPTC surprisingly has herbicidal power not possesed by either component employed separately.When, in accordance with the invention, an herbicidal s-triazine compound is combined with EPTC, there is produced an herbicidal combination which is more effective as a weed killer than either herbicide alone. In combination, these two types of herbicides co-act to give synergistic herbicidal activity. The result is that the combination has enhanced herbicidal effectiveness giving better kill and less regrowth using smaller amounts of the combination than by using either herbicidal component separately at equivalent rates.
