Polymer particles with poly[(acylimino)ethylene] chains on the surface were prepared by soapfree emulsion copolymerization of styrene with a styryl-type poly[(acylimino)ethylene] macromonomer. The macromonomer used was highly hydrophilic and soluble in water. The contour of the particles was d n e d by scanning electron microscopy. The copolymer particles were spherical and monodisperse. The average diameter of the particles was in the sub-micron range and smaller than that of pure polystyrene particles prepared in a similar way. The surface composition of the particles was analyzed by ESCA (electron spectroscopy for chemical application). It was found that poly[(acylimino)ethylene] chains are enriched on the particle surface.

Carbamoyl phosphonate derivatives of methacrylic acid and α‐methyl styrene were synthesized in good yield by reacting dimethyl and diethylphosphite with isocyanato ethylmethacrylate (IEM) or with meta‐isopropenyl‐α,α‐dimethylbenzylisocyanate (m‐TMI). The IEM derivatives yield soluble homopolymers with common radical initiators. The m‐TMI carbamoyl phosphonates were copolymerized with styrene and with acrylates yielding soluble materials with better than 50 mol % incorporation of the phosphonate monomer. The side chain carbamoyl phosphonate group drastically lowers the Tg relative to those of the parent polymers. Thermogravimetric studies suggest the NHC(O)P(O)(OR)2 bond to be stable to about 225°C. The radiopacifying salt UO2(NO3)26 H2O yields transparent films with the phosphonate‐containing polymers. The Tg increases with uranyl content. © 1993 John Wiley & Sons, Inc.
