    摘要: 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.

    摘要: Disclosed is a free radical polymerization process for the preparation of a thermoplastic resin or resins comprising heating a mixture of a free radical initiator, a stable free radical agent, and at least one polymerizable monomer compound to form a thermoplastic resin or resins with a high monomer to polymer conversion; cooling said mixture; optionally isolating the thermoplastic resin or resins; and optionally washing and drying thermoplastic resin or resins.Related free radical processes are also disclosed for the preparation of mixtures and block copolymer thermoplastic resins. Resins prepared by the disclosed processes possesses a narrow polydispersity and a modality that is controlled by the selection of a free radical initiator and stable free radical agent addition step or steps.
