摘要： A process for latex preparation including: a first heating of a mixture of at least one free radical polymerizable monomer compound, a free radical initiator compound, and a stable free radical compound to form a latomer mixture with from about 1 to about 8 percent conversion of the monomer compound to an oligomeric compound of the formula I—R′—SFR, wherein R′ is an oligomer comprised of from about 1 to about 30 monomer units, I— is a covalently bonded free radical initiator fragment arising from the free radical initiator compound, and —SFR is a covalently bound stable free radical group; dispersing the resulting latomer mixture in water with high shear to form a miniemulsion; and a second heating of the miniemulsion, wherein there results a high stability polymer particle latex which contains a polymer with a high monomer to polymer conversion of from about 98 to about 100 weight percent and a narrow polydispersity of from about 1.1 to about 2.0.
