Research of Copolymerization Kinetics of CO and C_2H_4 Catalysed by Palladium

摘要

A dynamical behavior about preparation polyketone from Carbon monoxide and ethene alternately copolymerization in methanol by catalyst cantained palladium acetate and DPPP was detailed represented in this paper. The synthesis mechanism of PK has been studied detailed, and a kinetic model equation is established, and the model parameter was determination. The product(PK) is not strictly alternating copolymerization, and their molecule chain cantained main -(CH_2CH_2CO)_n~-, and presence of a small amount of -CH_2CH_2CH_2CH_2CO-. The results showed that dynamical equation of the CO/C_2H_2 copolymerization to PK have corresponded with experiment data very well. In other words the kinetic equation of CO/C_2H_2 alternate copolymerization by Pd(AeO)/DPPP catalyst can used to describe their reaction behavior.
