Effects of Hydrophobic Groups Content and Micro-block Length on the Elasticity of Associative Polymer Solution
Abstract:
The effects of hydrophobic group content and micro-block length on viscoelastic properties of P(AM-NaAA-C16DMAAC) (AA:acrylamide, NaAA:sodium acrylate,C16DMAAC:hexadecyl trimethyl allylammonium chloride) solution were studied. The results indicated that the viscoelastic properties could be changed effectively for associative polymers with similar molecular structure and common zero shear viscosity by varying the molecular structures. When increasing the hydrophobic group content,the first normal stress difference (N1) increased and its shearing rate,a speed for N1 to reach the minimum value decreased. Furthermore,when increasing the micro-block length,the viscosities and the viscoelatic rheological properties decreased after initial increasing,so there is an optimum value for the micro-block length.
