Abstract: Novel ketone monomers containing both alpha-beta unsaturated acylate and unsaturated fatty acylate substituents on more carbon atoms beta to the carbonyl group (Formula 1) have been found to be surprisingly useful in a variety of essentially pollution free coatings applications.a,b,cCC(0)Cd,e,f Formula IWherein not less than one, but no more than three of a,b,d and e are each independently chosen from among monovalent ligands having the structure --CH.sub.2,O.sub.2 CCR.dbd.CR'R" (wherein each of R,R', and R" is independently chosen from among hydrogen, methyl or ethyl ligands); and wherein at least one, but not more than three of a,b,d and e are each independently chosen from among monovalent ligands having the structure: --CH.sub.2 O.sub.2 CC.sub.n H.sub.

Abstract: Apparatus and processes are disclosed for treating materials by exposure thereof to sonic or ultrasonic oscillations produced by oscillating plates which form part of a processing chamber and which are each activated by a plurality of transducers adjacent thereto. The transducers are excited by an electronic circuit capable of driving each transducer at selectable frequencies, phase relationships and amplitudes. The invention also comprises processes for the treatment of materials by exposure thereof to oscillating plates excited at predetermined combinations of frequencies, phases and amplitudes.
