    • A process for the preparation of a thermoplastic resin, or thermoplastic resins comprising: forming, or providing a miniemulsion comprised of a mixture of an oligomeric compound of the formula R—SFR, wherein R is an oligomeric compound comprised of from about 1 to about 30 monomer units and optionally a covalently bonded free radical initiator compound, —SFR is a covalently bound stable free radical end group, and at least one free radical polymerizable monomer compound, and a surfactant; and heating the miniemulsion wherein there results a latex thermoplastic resin or a latex of thermoplastic resins with a high monomer to polymer conversion of about 85 to about 100 percent and a narrow polydispersity of from about 1.1 to about 2.0.

    • 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.
    • 一种用于胶乳制备的方法,包括:首先加热至少一种可自由基聚合的单体化合物,自由基引发剂化合物和稳定的自由基化合物的混合物以形成卡波姆混合物,其中约1至约8%的转化率 单体化合物与式I-R'-SFR的低聚化合物反应,其中R'是由约1至约30个单体单元组成的低聚物,I-是自由基引发剂产生的共价键合的自由基引发剂片段 化合物,-SFR是共价结合的稳定自由基; 将所得的卡波姆混合物以高剪切力分散在水中以形成细乳液; 和小乳液的第二次加热,其中产生高稳定性聚合物颗粒胶乳,其包含具有约98至约100重量%的高单体与聚合物转化率和约1.1至约2.0的窄多分散性的聚合物。
