WebAfter computation of the interfacial tension between the constituent polymers, PET and PLA have the smallest value referring to preferential miscibility between them over EBA–GMA. This infers that the PLA chains will tend to form droplets within the PET matrix phase. On the contrary, EBA–GMA will remain immiscible in the blends when present ... In general, such PET is known as PETG or PET-G (polyethylene terephthalate glycol-modified). It is a clear amorphous thermoplastic that can be injection-molded, sheet-extruded or extruded as filament for 3D printing. PETG can be colored during processing.

Web1. jan 2015 · Copolyesters from PET and Aliphatic Renewable-Based Comonomers This section deals with PET copolymerization with an adequate comonomer (s). This strategy is particularly advantageous if the comonomer (s) is/are from renewable origin, hence imparting to the ensuing copolyesters a partially renewable nature. A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols. For example, by introducing other diacids, such as isophthalic acid (IPA), or other diols, such as cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET), the material becomes a copolyester due to its comonomer content. Copolyesters retain their strength, clarity, and other mechanical properties even when exposed t…
