PARTICULATE RESIN, FRICTION PARTICLE, FRICTION ELEMENT AND PROCESS FOR PRODUCTION OF PARTICULATE RESIN

摘要

There are disclosed compositions useful as friction particles comprised of tri- and/or tetrafunctional phenol, difunctional phenol, aldehyde, a protective colloid, and a reaction promoting compound. There are also disclosed friction elements formulated from said compositions and also a process for producing the friction particles in particulate form.
