Sandstedt D. I, Smalley The attached article from the May "Chemecology" regarding dispersion stripping is very interesting. Do we know any more about Diamond's technique? We still are not completely satisfied with the nitrogen sparge or Fryma techniques as being processes we can ultimately live with. This process may offer some real advantages. JWP:gm 7 3. W. Poarch COLOR!TE 017429  Technique Cuts VC in Dispersion Resins The Diamond Shamrock Corporation's plastics division says it has a proprietary technique for removing residual vinyl chlo ride monomer from polyvinyl chloride dis persion resins. The new technology has been tested on a commercial scale at the company's own dispersion resin facilities. Harry Connors, vice president and gen eral manager of the plastics division, says "performance to date has shown that this technique is more than capable of meet ing proposed Environmental Protection Agency standards for VCM levels in disparsion resin latex. We feel this is the first technology available for dispersion resins that does not cause coagulation in this finely dispersed material or cause any subsequent adverse effect on properties." Mr. Connors said the new technology will be made available industrywide for a license fee to help defray developmental costs. PVC dispersion resins are used for coat ing fabric, creating the "leather" look for clothing, upholstery and wallpaper. F i r 1 { i 1 | i COLORITE 017430
