Claim 1

A FRICTION PARTICLE COMPRISING A NON-CATALYZED PRODUCT OF THE REACTION AT ABOUT 225* TO ABOUT 400*F. OF A NON-HYDROXYALKYLATED, HYDROXY AROMATIC HYDROCARBON-ALDEHYDE RESOLE CONTAINING SUBSTANTIALLY NO ETHERIFIED AROMATIC HYDROXYL GROUP WITH AN ALKYLATED HYDROXY AROMATIC HYDROCARBONALDEHYDE RESOLE, UNTIL THE RESULTING PRODUCT IS SUBSTANTIALLY INSOLUBLE IN ACETONE, INFUSIBLE, AND DOES NOT SOFTEN SLIGHTLY UNDER MECHANICAL FORCE AT A TEMPERATURE BELOW 400*F. AND HAS SUBSTANTIALLY NO COHESIVE OR BONDING STRENGTH, WHEREIN SAID NON-HYDROXYALKYLATED RESOLE COMPRIESE ABOUT 60 TO ABOUT 95% OF THE WEIGHT OF THE RESIN COMPONENTS, WHEREIN THE ALKYLATED GROUPS ARE SUBSTITUTED ON THE AROMATIC RING AND ARE SELECTED FROM THE GROUP CONSISTING OF: A. ALKYL GROUPS OF 1 TO 60 CARBON ATOMS, B. CYCLOALKYL GROUPS OF 5 TO 12 CARBON ATOMS, C. ALKYL, ARYL AND CYCLOALKYL KETONIC GROUPS WHEREIN THE HYDROCARBON PORTION IS AS DEFINED IN (A) AND (B), D. ALKYL, ARYL AND CYCLOALKYL CARBOXYLIC GROUPS WHEREIN THE HYDROCARBON PORTION IS AS DEFINED IN (A) AND (B), E. ARYL GROUPS OF 6 TO 24 CARBON ATOMS, AND F. ARYL SUBSTITUTED ALKYL WHEREIN THE ARYL IS PHENYL, LOWER ALKYL-SUBSTITUTED PHENYL OR HYDROXY SUBSTITUTED PHENYL.
