Embodiment 1

[0187] Example 1: General Procedure for Preparation of Polymeric Plasticizer Compositions

[0188] Polymeric plasticizer compositions were made using the general procedure described below.

[0189] Procedure when the source of aromatic acid is an aromatic diacid or ester or anhydride

[0190] Aromatic acid source, dihydric alcohol and C 4 -C 36 The monocarboxylic acid or its ester or anhydride was charged into a 4 neck round bottom flask reactor which was then placed in a heating mantle connected to a temperature controller. Connect the nitrogen inlet, thermocouple, and mechanical stirrer to the reactor. The reaction was carried out at 189-250°C under a nitrogen purge. When the appropriate acidity was reached by sampling and measuring the acid ester, the reaction was terminated and property studies were performed.

[0245] Example 3: Plasticized polyethylene terephthalate (PET) composition

[0246] 100 grams each of the PET pellets and the polymeric plasticizer composition 6 described in Example 1 were charged into a 500 mL 4 necked round bottom flask. The mixture was placed under a nitrogen atmosphere and heated at a temperature of 220°C with slow stirring until the particles were completely dissolved. The temperature of the reaction mixture was cooled to 200°C and poured into a Teflon pan to form an opaque tan material.

Abstract

The present invention relates to polymeric plasticizer compositions made from an aromatic acid source, a glycol, and a C4 - C36 monocarboxylic acid, or ester or anhydride thereof. The aromatic acid source can include polymeric materials such as recycled polyethylene terephthalate (PET). The present invention also relates to methods for making the polymeric plasticizer compositions, to methods of plasticizing polymeric materials, and to plasticized polymeric compositions. The polymeric plasticizers are useful for plasticizing various polymers, such as thermoplastic polymers, including, for example, polyvinyl chloride (PVC). The polymeric plasticizers provide a sustainable alternative to conventional phthalate ester plasticizers, such as diisooctyl phthalate (DOP).
