Estimating the term…
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.
A free radical polymerization process for the preparation of a thermoplastic resin or resins comprising:
A free radical polymerization process for the preparation of a thermoplastic resin or resins comprising:
A free radical polymerization process for the preparation of a thermoplastic resin or resins comprising heating from about 100.degree. to about 160.degree. C. a mixture comprised of a free radical initiator, a stable free radical agent, and at least one polymerizable monomer compound to form said thermoplastic resin or resins with a polydispersity of from about 1.1 to about 1.45.
A polymerization process for the preparation of a thermoplastic resin or resins comprising heating from about 100.degree. to about 160.degree. C. a mixture comprised of a free radical initiator, a stable free radical agent, and at least one polymerizable monomer compound to form said thermoplastic resin or resins with a monomer to polymer conversion of from about 10 to about 100 percent and a polydispersity of from about 1.1 to about 1.45.
