Poly(ethylene-co-acrylic acid)
Poly(ethylene-co-acrylic acid) (CAS: 9010-77-9) is a copolymer synthesized from ethylene and acrylic acid, typically supplied as beads. This material functions as a processing and performance additive in plastics. Its carboxylic acid groups enhance compatibility and dispersion of other additives, while its ethylene backbone provides a hydrophobic character. It is particularly noted for its ability to promote crystallization in polyethylene terephthalate (PET) and improve the overall processing of various polymer systems.

Polymer Crystallization Promoter
This copolymer is effective in promoting the crystallization of polymers like PET. By acting as a nucleating agent, it can influence the morphology and properties of the final plastic product.
Additive Dispersion Aid
The presence of acrylic acid units in the polymer chain aids in the dispersion of various additives within plastic matrices. This leads to a more homogeneous distribution of fillers, pigments, or other modifiers.
Processing Aid
It can be utilized as a processing additive to improve melt flow and handling characteristics during polymer processing operations, potentially reducing processing temperatures or times.
