The effect of the structure of aromatic acrylate-fluoroacrylate copolymers on CO2 viscosity at elevated pressures was investigated. These copolymers were all found to be miscible with CO2 at pressures between 10-15 MPa (295 K) and induce an increase in the viscosity to some degree. It appears that stacking of aromatic rings is the key factor in viscosity enhancement. The results showed that viscosity of the solution increases with the increasing content of the aromatic acrylate unit in the copolymer, but a point is reached beyond which addnl. comonomer causes the relative viscosity to drop, suggesting that the aromatic rings associate through intramol. rather than intermol. interactions beyond the optimum value. The most effective CO2 thickener identified in this study was the 29% Ph acrylate-71% fluoroacrylate copolymer. However, the presence of a spacer (Me or ethyl) between the backbone and the aromatic group substantially diminished the viscosity enhancement. In the experimental materials used by the author, we found Benzyl acrylate(cas: 2495-35-4Reference of Benzyl acrylate)
Benzyl acrylate(cas: 2495-35-4) has been used in preparation of high refractive index polyacrylates. Benzyl acrylate is used in the preparation of heptanoic acid benzyl ester. It is used to prepare polybenzylacrylate using azobisisobutyronitrile as initiator.Reference of Benzyl acrylate
