초록 ▼

A polymerization process comprising: heating a mixture comprised of a free radical initiator, a stable free radical agent, at least one polymerizable monomer compound, and optionally a solvent, to form a polymer with a high monomer to polymer conversion and a narrow polydispersity, wherein said polymer is comprised of a covalently bound free radical initiator fragment at one end and a covalently bound stable free radical compound at the other end of the polymer, and wherein said stable free radical agent has high thermal, acidic, and photochemical stability.

대표청구항 ▼

A polymerization process comprising: heating a mixture comprised of a free radical initiator, a non-nitroxide type stable free radical agent, at least one polymerizable monomer compound, and optionally a solvent, to form a polymer with a monomer to polymer conversion of from about 50 to about 100 percent and a polydispersity of from about 1.0 to about 2.0, wherein said polymer is comprised of a covalently bound free radical initiator fragment at one end and a covalently bound non-nitroxide type stable free radical moiety at the other end of the polymer, and wherein said non-nitroxide type stable free radical agent has thermal, acidic, and photochemical stability which is greater than the corresponding nitroxide type stable free radical agent.
