Abstract
Intimate blends of macrocyclic oligomer compositions, such as cyclic polycarbonate or poly(alkylene dicarboxylate) oligomer mixtures, are blended with linear polymers, especially addition polymers. The blends flow easily and are frequently homogeneous. The macrocyclic oligomers therein may be polymerized to produce resin blends having advantageous properties.
