## Abstract Monodisperse micron‐sized styrene–acrylonitrile copolymer (SAN) particles were prepared by a seeded swelling and polymerization method. Polystyrene particles prepared by dispersion polymerization were used as the seed latex. Characteristics of the particles were examined by scanning ele

A new type of catalyst for the hydrosilylation of unsaturated monomers with dichloromethylsilane (DCMS) was prepared, which consisted of thiolmethylene-substituted styrene-divinyl benzene copolymer and platinum. When using DCMS as a hydrosilylation agent, these catalysts showed a high activity in th
## 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 monodispe
Styrene-methacrylic acid copolymer [P(S-MAA)] (92/8, molar ratio) nanoparticles were prepared by a dissolution of submicron-sized P(S-MAA) particles with various molecular weights in a polyoxyethylene nonylphenylether nonionic emulsifier aqueous solution at pH 13.0 and above 90ЊC. The latter particl
