✦ Synopsis


A cationic polymer of n-butyl methacrylate was prepared in an emulsifierfree system. Using, as a base, a 30% solid content, the variables studied were the monomer and initiator concentrations, the agitation, and the temperature. The molecular weight, the zeta potential, and the particle size were determined. The results are compared with earlier work done on similar systems.

## Abstract A modified emulsifier‐free emulsion polymerization of butyl methacrylate (BMA) with ionic or/and nonionic comonomers was successfully used to prepare nanosized poly(butyl methacrylate) (PBMA) latices with high polymer contents. After seeding particles were generated in an initial emulsi
