Abstract:
Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

Claim (Index 24):
A method to control resistance to flow and/or flow rate enhancement of a non-polar composition alone or in combination another physical and/or chemical property of the non-polar composition, the method comprising\n providing a host composition having a dielectric constant equal to or less than about 5; providing at least one framing associative polymer substantially soluble in the host composition, the at least one framing associative polymer having a weight averaged molecular weight equal to or higher to 200,000 g/mol; and combining the host composition and the at least one framing associative polymer at a concentration c selected between from about 0.001 c* to 1c*, depending on the weight averaged molecular weight and/or Radius of gyration of the at least one framing associative polymer and on a physical and/or chemical property to be controlled, wherein c * = 3 \ue89e M w 4 \ue89e \u03c0 \ue8a0 ( R g 2 ) 3 / 2 \ue89e N a , in which M w  is the weight averaged molecular weight, R g  is the radius of gyration, and N a  is Avogadro's constant; wherein the at least one framing associative polymer comprises: a linear, branched, or hyperbranched polymer backbone having at least two ends and a functional group presented at two or more ends of the at least two ends of the linear, branched, or hyperbranched polymer backbone; wherein the linear, branched, or hyperbranched polymer backbone is substantially soluble in a non-polar composition, and wherein a number of the functional groups presented at the two or more ends is formed by associative functional groups each capable of undergoing an associative interaction with another associative functional group in the non-polar composition with an association constant (k) wherein k \ue8a0 ( M - 1 ) \u2265 4 3 \ue89e \u03c0 \ue8a0 ( R g 2 ) 3 2 \ue89e N a n F \u00d7 10 - 23 in which R g  is the radius of gyration of the framing associative polymer in the non-polar composition in nanometers, N a  is Avogadro's constant; and n F  is the average number of the associative functional groups in the framing associative polymer.
