ABSTRACT:
The present invention is drawn to a surfactant initiator. The surfactant initiator includes a first hydrophilic chemical group bonded to a first hydrophobic chemical group to form a first portion. A second portion is also included, made up of a second hydrophilic chemical group bonded to a second hydrophobic chemical group. A homolytic cleavable group chemically bonds the first and second portions. At least one of the first and second portions is configured to initiate free-radical polymerization upon separation of the homolytic cleavable group. Such surfactant initiators can be used to produce latex particulates and associated suspensions and inks.
