The present invention relates to multi-arm star macromolecules which are used as thickening agents or rheology modifiers, including use in hydraulic fracturing fluid compositions. In one aspect of the invention, a star macromolecule is capable of thickening via a dual mechanism comprising (1) self-assembly of the hydrophobic polymerized segments of the star macromolecules via hydrophobic interactions or associations, and (2) association, reaction, or combination of the hydroxyl-containing polymerized segments of one or more of the star macromolecules.
本发明涉及用作增稠剂或流变修饰剂的多臂星型大分子,包括用于水力压裂液组合物中。在本发明的一个方面,星型大分子能够通过双重机制增稠,其中包括:(1)星型大分子的疏水聚合段通过疏水相互作用或结合进行自组装,以及(2)一个或多个星型大分子的含羟基聚合段的结合、反应或组合。
