Abstract We describe the use of small-angle neutron scattering (SANS) to measure the average radius of polystyrene particles in the early stages of emulsion polymerization. Polymerization was started by placing monomer in contact with an aqueous polyacrylamide gel containing intiator, in the absence of sufractant. Reaction was allowed to occur for 12, 24 and 48 h, and slices were removed from the gels in each system at various distances (of order 10 mm) from the interface. SANS meausrements on these slices showed the presence of particles of radius 6 ± 1 nm. These experiments show that, in these systems, one can halt the growth (by propagation and coagulation) of very small colloidal particles for a sufficiently long time to measure physical properties such as the amount of monomer imbibed at equilibrium swelling, surface charge, etc.
