In situ polymerization of surface-active agents on latex particles II. The mechanical stability of styrene/butadiene latexes

The polymerization of sodium 9-(and 10)-acrylamidostearate (NaAAS) which was adsorbed in varied amounts on the surface of a relatively unstable styrene/butadiene (60/40) copolymer latex resulted in latexes the mechanical stability of which was slightly lower at low coverages but definitely higher at intermediate and high coverages than that of latexes with equivalent amounts of adsorbed monomeric NaAAS.
