Abstract:
1. A thermally-reversible, aroma-releasing PVC thermoplastic polymeric matrix gel composition made by the process comprising the steps of: (a) a first step of creating a homogenous liquid solution comprising (b) a second step wherein the homogenous liquid solution from step (a) is heated by pumping through a first closed-loop heat exchanger to a temperature of from about 280° F. to about 330° F.; followed by (c) a third step wherein the homogenous liquid solution from step (b) is cooled by pumping through a second closed-loop heat exchanger to a temperature of from about 130° F. to about 200° F., thereby forming a thermally-reversible, aroma-releasing PVC thermoplastic polymeric matrix gel composition.
