Abstract

Polystyrene(PS)‐based latex particles bearing amino groups have been prepared using a two‐step process consisting of seeded copolymerization of a monomer mixture with styrene (S) and either 4‐vinylbenzylamine (VBA) or its trifluoroacetamide derivative (VBAF) in the presence of monodisperse PS latex. Poor colloidal properties and bad chemical stability were found in the case of latexes obtained with VBA. Better results were obtained with VBAF, but conversion was not completed. Surface characterization of the final latexes by ^1^H NMR, XPS and colorimetric titration offer some insight into the location of the VBAF monomer units within the particles.

## Abstract Kinetics of radically initiated solution homopolymerization of 4‐vinylbenzylamine (VBA) and its trifluoroacetamide derivative (VBAF), and their copolymerization with styrene (S), have been investigated at 60°C in toluene and DMSO, respectively, using AIBN as initiator. __k__~p~/__k__~t~
