交联聚合物微球-聚合物在水溶液中的复合

Hydrophobic associating polymer has special rheological properties because the hydrophobic groups in aqueous solution produce hydrophobic association with eeach other so that supramolecular structures can form . In order to examine rheological properties of aqueous polymer composite system composed of cross-link polymer microspheres and polymers, in this paper the composite forms of cross-linked polymer microspheres and polymers in the aqueous solution are observed by the environmental scanning electron microscope (ESEM) through adopting the experimental method of rapid freezing and sublimation for the first time. The viscosity- concentration property and viscosity shear recovery ability of the compound system are also determined. The results prove preliminarily that there exist synergistic effects between the hydrophobic associated polymer (AP - P4) and cross-linked polymer microspheres, and all these work would lay a foundation to further explore the mechanism of compound system.
