Abstract:
The present invention relates to copolymer process aids having a carboxylic anhydride or acid functionality and a hydrophobic functionality. The copolymer process aid can be used in the exfoliation of a nanoclay, where it can be made in situ; and can also serve as a compatibilizer for exfoliated nanoclays with a polymer matrix, including with impact modified polymer matrices.
