Patent ID: 8440297

Claim:
A polymer organoclay composite comprising a molecularly self-assembling (MSA) material and an organoclay dispersed in the MSA material, wherein the organoclay comprises a cation exchanging layered material and organic cations, the cation exchanging layered material having a cation exchanging capacity that is at least 1 mole percent (mol %) exchanged with the organic cations, the organoclay comprising from 1 weight percent (wt %) to 70 wt % of the polymer organoclay composite based on total weight of the polymer organoclay composite wherein the molecularly self-assembling material comprises repeat units of formula I: and at least one second repeat unit selected from the ester-amide units of Formula II and III: and the ester-urethane units of Formula IV: or combinations thereof wherein: R is at each occurrence, independently a C 2 -C 20 non-aromatic hydrocarbylene group, a C 2 -C 20 non-aromatic heterohydrocarbylene group, or a polyalkylene oxide group having a group molecular weight of from about 100 grams per mole to about 5000 grams per mole; R 1 at each occurrence independently is a bond or a C 1 -C 20 non-aromatic hydrocarbylene group; R 2 at each occurrence independently is a C 1 -C 20 non-aromatic hydrocarbylene group; R N is —N(R 3 )—Ra—N(R 3 )—, where R 3 at each occurrence independently is H or a C 1 -C 6 alkylene and Ra is a C 2 -C 20 non-aromatic hydrocarbylene group, or R N is a C 2 -C 20 heterocycloalkyl group containing the two nitrogen atoms, wherein each nitrogen atom is bonded to a carbonyl group according to formula (III) above; n is at least 1 and has a mean value less than 2; and w represents the ester mol fraction of Formula I, and x, y and z represent the amide or urethane mole fractions of Formulas II, III, and IV, respectively, where w+x+y+z=1, and 0<w≦1, and at least one of x, y and z is greater than zero but less than 1.
