Abstract
Described herein are associative polymers capable of controlling one or more physical and/or chemical properties of non-polar compositions and related compositions, methods and systems.
Claims21
A non-polar composition comprising:
- a host composition having a dielectric constant equal to or less than about 5 and
- at least one associative polymer, soluble in the host composition,
- wherein the at least one associative polymer is comprised in the host composition in a concentration between from about 0.1c* to about 10c* wherein

- wherein Mw is the weight averaged molecular weight, Rg is the radius of gyration, and Na is Avogadro's constant
- wherein the at least one 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 backbone,
- and wherein the linear, branched, or hyperbranched polymer backbone is substantially soluble in a non-polar composition, and the functional group is capable of undergoing an associative interaction with another functional group with an association constant (k) of from 0.1<log10k<18.
