1. A system for forming a multimodal Polyalkylene Terephthalate (PAT), the system comprising:
a first feed having a low molecular weight (LMW) PAT, the LMW PAT having a low average molecular weight, wherein the LMW PAT includes a degrading molecule;
a second feed having a high molecular weight (HMW) PAT, the HMW PAT having a high average molecular weight, wherein the low average molecular weight is lower than the high average molecular weight;
a mixer configured to receive the first feed and the second feed in order to mix the LMW PAT and HMW PAT; and
an output having multimodal PAT, wherein the multimodal PAT includes the degrading molecule, and wherein the multimodal PAT comprises:
a first distribution of the LMW PAT mixed with a second distribution of the HMW PAT to have a multimodal distribution of LMW PAT and HMW PAT.
