Impact modification of polyamide-12 through blending with liquid polybutadiene, 2 ^a Compatibilization of blends of PA12 and liquid polybutadiene with pyromellitic anhydride

e-Polymers, 2003
Abstract The compatibilizing effect of pyromellitic anhydride (APy) in blends of PA12 and liquid polybutadiene (HTPB) was investigated. Blends were prepared, with or without APy, and the efficiency of this route of compatibilization was evidenced by observation of their morphologies.
