NEW ISOPAR isoparatfinic hydrocarbons M a n y products yet unborn are now commercially possible with this new family of high-purity isoparaffinic hydrocarbons. Con structed by catalytic synthesis, Isopar presents a unique chal lenge. For the first time its useful set of properties is available in commercial quantities for the chemical industry. Applications are virtually infinite! I N P O L Y O L E F I N R E A C T I O N S , as a high-purity diluent, Isopar offers good polymer yields with low catalyst consump tion. Isopar gives adequate solvency for catalysts and mono mers; has unique solvency properties in stereo rubber solution systems—also minimum solvency for slurried type polymers. Several narrow-range grades of stepped volatility help optimize separation and recovery. For free brochure, "Isopar," write to our Solvent Sales Department in Houston, Texas. "Trademark.
