New way to get heavier, faster-linking vinyl polymers A new development* employing Glycerine to speed up the formation of high-molecular-weight vinyl polymers holds out the promise of plastics with new and unusual properties. The process makes use of Glycerine's ability to increase the true, or local, viscosity of the solvent. This increased local viscosity acts to suppress the termination step of the polymerization reaction. Of all the thickening agents tested, only Glycerine had this effect. The reaction brought about with this new proc ess is claimed to yield polymers with molecular weights far in excess of those obtained by conven tional methods. Work is under way to develop Commercial possibilities of these new polymers.
Glycerine's usefulness continues to grow. Stable in price, dependable in supply, Glycerine offers processors a unique balance of properties: It is hygroscopic, nontoxic, stable, nonvolatile, with excellent solvent power and agreeable taste. New applications for Glycerine are extending its use in paints, foods, pharmaceuticals, packaging and many other fields. For a handy 20-page booklet, "Glycerine Properties and Uses," write to:
