Question
Consider synthesis of poly(ethylene terephthalate) by polyesterification. Rate constants for polyesterification are 10^-2 (L mol^-1)2 s^-1 (no catalyst added) and 2x10^-2 L mol^-1s^-1 (catalyst added).
Consider synthesis of poly(ethylene terephthalate) by polyesterification. Rate constants for polyesterification are 10^-2 (L mol^-1)2 s^-1 (no catalyst added) and 2x10^-2 L mol^-1s^-1 (catalyst added).
A) How long would it take to prepare a polyester of weight average molecular weight 3,000 under each set of conditions? Given that the initial dicarbixilic acid concentration is 3 mol L^-1.
B)If 5 mol% excess of diol were to be used in the previous problem, what number average molecular weight would be obtained if the reactions were carried to the same conversion?
