Unique Additives for Polymer Modification

Compatibilizers

Compatibilizers are analogous to coupling agents. They diffuse to the interface between two incompatible polymers and interact with each to improve dispersion and adhesion. They also reduce the dispersed phase domain size, producing better impact resistance and elongation to break. See Figure 2.
