Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions that can be used when the non-polar composition is in a flow, and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone with a longest span having a molecular weight that remains substantially unchanged under the flow conditions 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.
本文描述的是能够控制非极性组合物的物理和/或化学性质的缔合聚合物,当非极性组合物处于流动状态时可以使用,以及相关的组合物、方法和系统。本文所述的缔合聚合物具有非极性骨架,其最长跨度的分子量在流动条件下基本保持不变,官能团位于非极性骨架的两端、在非极性骨架两端的官能团中,有一些官能团是由能与另一个官能团发生缔合作用的缔合官能团形成的,其缔合常数(k)使每个缔合作用的强度小于原子间共价键的强度,特别是小于骨架原子间共价键的强度。
