Abstract
The present invention provides a process for measuring and controlling chemical reactions that produce thermoplastic polymers by utilizing a stoichiometry correction during a reaction cycle to produce thermoplastic resins with desired properties. The thermoplastic polymer is made from at least one first monomer having a first reactive end group and at least one second monomer having a second reactive end group by reaction of the first reactive end group with the second reactive end group and has a glass transition temperature of greater than 130° C.
