✦ Synopsis

Emulsion copolymerization of silicones (octomethyl tetracyclosiloxane, D , and methac yloxypropyl trimethoxy silane, M A T S ) and acrylics was carried out using three different polymerization processes: semicontinuous monomer emulsion addition, batch and initiator solution addition. Results showed that only the semicontinuous process led to a stable latex with monodisperse particles.

Various polymerizations were carried out through this process with varying siliconelac y l i c ratios and MATS content. Films were obtained from different latexes: their properties are significantly influenced by silicone and MATS contents in copolymers.
