Claims
- 1. A method of forming a polymer comprising the steps of:
- (a) feeding a predetermined amount or rate of a gaseous oxidant and a predetermined amount or rate of hydrocarbon into the reaction zone, the reaction zone attaining a first pressure;
- (b) measuring a rate of a pressure-drop during the reaction by conducting at least one step of
- (i) allowing the gaseous oxidant to cause a reaction in a manner that the reaction zone attains a second pressure, lower than the first pressure, at least partially resulting from the reaction;
- (ii) allowing the gaseous oxidant to cause a reaction and measuring the pressure drop within a predetermined interval of time;
- (c) adjusting the rate of the pressure-drop within a desired range by regulating a parameter in the reaction zone selected from a group consisting of temperature, feed of gaseous oxidant, composition of gaseous oxidant, pressure, feed of hydrocarbon, feed of solvent, feed of catalyst, feed of promoter, and a combination thereof;
- (d) repeating steps (a) to (c);
- (e) continuing repeating steps (a) to (c);
- wherein the intermediate oxidation product comprises a compound selected from a group consisting of adipic acid, phthalic acid, isophthalic acid, and terephthalic acid, and the method further comprises a step of reacting said intermediate oxidation product with a third reactant selected from a group consisting of a polyol, a polyamine, and a polyamide in a manner to form a polymer of a polyester, or a polyamide, or a (polyimide and/or polyamideimide), respectively.
- 2. A method as defined in claim 1, further comprising a step of spinning the polymer into fibers.
