Fig. 1. Integrated circular materials economy based upon the prenolysis of PET.

Fig. 1.

Reaction of PET with prenol affords BPreT, which can either be used to synthesize PET (by reaction with EG) or PET-derived networks and photoresins for additive manufacturing. Treating BPreT networks with prenol reformed BPreT, closing the loop.
