NEW TSOPAR isoparaffinic hydrocarbons Many products yet unborn are now commercially possible with this new family of high-purity isoparaffinic hydrocarbons. Constructed by catalytic synthesis, Isopar presents a unique challenge. For the first time its useful set of properties is available in commercial quantities for the chemical industry. Applications are virtually infinite! IN POLYOLEFIN REACTIONS, as a high-purity diluent, Isopar offers good polymer yields with low catalyst consumption. Isopar gives adequate solvency for catalysts and monomers; 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.

P U R I T Y —aromatics — only a few parts per thousand • Sulfur, carbonyls, chlorides, peroxides—only a few parts per m i l l i o n • n o n - v o l a t i l e c o n t e n t — p r a c t i c a l l y n i l . FRACTIONATION — excellent, several narrow-range fractions boiling between 120°F and 500°F. REACTIVITY — i n e r t to m a n y polyolefin c a t a l y s t s and r e a c t i o n s . SOLVENCY—highly selective. ODOR AND C O L O R — nearly nil (mild, pleasant odor with lighter fractions). STABILITY —excellent. LOW TOXIC HAZARD—least harmful of hydrocarbons of equivalent volatility tested.
