Abstract
The invention relates to polymers derived from macrocyclic oligomers containing organo clay fillers comprising a) a polymer derived from a macrocyclic oligomer; b) clay platelets; and c) the residue of one or more onium compounds having at least one ligand with a Cor greater carbon chain and at least one ligand containing one or more functional groups having one or more active hydrogen atoms wherein the functional group is reactive with the macrocyclic oligomer and/or functional groups formed when the macrocyclic oligomer decyclizes wherein a portion of one or more of the onium compounds is ironically bound to the clay platelet and covalently bonded to the polymers derived from macrocyclic oligomers. The invention also relates to processes for preparing such compositions. Furthermore, the invention relates to articles prepared from organoclay filled polymer compositions.
