Solution Behaviour of a Random Copolymer of Poly(Isobutyl Methacrylate- t-Butylaminoethyl Methacrylate). 2. Viscosity and Light Scattering Intensity Studies

Abstract

Random copolymers of (isobutyl methacrylate and t-butylaminoethyl methacrylate (poly(iBMA-tBAEMA)) have been used successfully as polymer additives for lubricants and coating materials in order to influence the fluid viscosity in polar and aprotic solvents under different conditions. However, poly(iBMA-tBAEMA) has been very difficult to characterize because of its aggregation behaviour due to intramolecular/intermolecular interactions, which are responsible for its utility as a polymer additive in the first place. The solution behaviour of poly(iBMA-tBAEMA) has recently been investigated by means of laser light scattering (LLS). The key to such a successful LLS study is the coincidental isorefractive nature of homopolymers of poly(iBMA) and poly(tBAEMA) and of the random copolymer poly(iBMA-tBAEMA). Reprints.
