Polyketones and polysulfones for conservation in the ethylene polymer industry. Progress report No. 4, January-March 1979
The objectives of this program are to: (1) prepare polyketones and polysulfones by the partial substitution of CO or SO/sub 2/ for ethylene; and (2) determine their market value as low-cost energy-conserving polymers. Additional quantities of Et-CO copolymers were prepared at 680 atm, as well as at 340 atm, by Co-60 gamma radiation induced polymerization for product evaluation by Tenneco Chemicals, Inc. (TCI). The preparative phase of the joint program with TCI is thus concluded. The final results and summary of the product evaluation study by TCI will be forthcoming shortly. Work was continued on polymerization rates for gas-phase Et-SO/sub 2/ mixtures at low pressure (< 10 atm) by Co-60 gamma radiation induced polymerization. Maximum rates were obtained in recharged vessels at SO/sub 2/ concentrations of < 5 mole % and at approximately 50 mole %. The peak rates appear to be directly proportional to the pressure. The peak G-values appear to be independent of pressure and are about the same for the two gas compositions, averaging approximately 8 x 10/sup 4/ molecules/100 eV.
