Abstract:
1. A process for preparing a monomer/polymer clay nanocomposite dispersion comprising the steps of A) providing a first aqueous dispersion of a natural or synthetic clay which can be partially intercalated and/or exfoliated and wherein said clay has an exchangeable cation; adding to said dispersion a compound of formula Ia, Ib, Ic, Id, Ie, II, IIIa, IIIb, IIIc, IIId, IIIe, IVa, Va, Vb, Vc, Vd or Ve and exchanging said cation at least partially and B) adding to said dispersion at least one ethylenically unsaturated monomer and polymerizing at least a portion of said ethylenically unsaturated monomer, wherein formula Ia, Ib, Ic, Id, Ie, II, IIIa, IIIb, IIIc, IIId, IIIe, IVa, Va, Vb, Vc, Vd and Ve are wherein T T T T T Q if Q if Q T T T or T T T Y is O or NR v is a number from 0 to 10 and w is 0 or 1; K K  where K where s and t are each a number from 0-4 and u is 1; or Z is —C(O)— or a direct bond, wherein if Z is —C(O)—, K if Z is a direct bond, K O—CH K —CH where s and t are each a number from 0-4 and u is 1; or a group —D R R R R R R R X where x is a number from 2 to 12; K R the alkyl groups are unsubstituted or substituted with one or more —OH, —COOH or C(O)R the aryl groups are phenyl or naphthyl which are unsubstituted or substituted with C and wherein in formula II G G G with the proviso that at least one of the 4 C L  phenylene or C Q L and the group —L
