Claim 0:
1. A system for controlling a physical and/or chemical property in a non-polar composition, the system comprising at least two between
at least one host composition having a dielectric constant equal to or less than 5, and
at least one framing associative polymer comprising
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 the at least one host 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 at least one host composition with an association constant (k) wherein, k
