Polyketones and Polysulfones for Conservation in the Ethylene Polymer Industry. Progress Report No. 3, October--December 1978.
- Tenneco Chemicals, Inc., Piscataway, NJ
The objectives of this program is to substitute relatively large quantities of CO into ethylene copolymers forming polyketones and determine their market value as a low cost and energy conservative polymer. Preliminary studies have also been performed with Et--SU/sub 2/ mixtures forming polysulfone copolymers. The work accomplished during this period is summarized below. Pound quantities of Et--CO copolymers have been produced at pressures of 680 atm with G-values range from 1000 to 3600. Oxygen acts as an inhibitor to polymerization. Tenneco Chmicals, Inc. is in the process of evaluating the properties of the copolymer. Et--CO gas copolymerized at low pressures in the order of 5 atm indicated low yields and produced a low molecular weight waxy material. Et--SO/sub 2/ copolymer can be produced at low pressure (<5 atm) in the gas phase by means of CO gamma radiation with chemical and physical properties that appear to be comparable to that of the copolymer made at higher pressure (>50 atm). the yield in terms of G-values are high ranging to 10,000. Oxygen which initially acts as an inhibitor on subsequent radiation may act as a catalyst enhancing the rate of polymerization. Et--SO/sub 2/ can be produced by thermocatalytic means, however, the most stable 1:1 Et--SO/sub 2/ copolymer was not produced. The properties of the copolymer have yet to be measured to determine the relative value of the thermal versus the radiation treatment.
