Abstract:

In the ARO project, we have succeeded in characterizing a random copolymer of polyisobutyl methacrylate-co-tertbutyl aminoethyl methacrylate, abbreviated as polyiBMA-tBAEMA in polar and protic solvents by means of laser light scattering LLS and viscosimetry. Intra- and intermolecular interactions could be used to explain the aggregation behavior which dominates the rheological properties of a large variety of such polymer solutions, making polyiBMA-tBAEMA a useful polymer additivethickening agent. By adding another polymer which can complex with polyiBMA-tBAEMA, we have found that the polymer can be used as a viscosity enhancer for the polymer additive, polyiBMA-tBAEMA. With sulfonated polystyrenes, the enhancement could reach a factor of 20.
