Claims
- 1. A process for preparing a polymer which comprises
- polymerizing at least one monomer M.sub.1, having a radically polymerizable unsaturated bond, in the presence of a monomer M.sub.2, which is different from said monomer M.sub.1, a radical generating source and an iodide compound having a cleavable carbon-iodine bond and capable of producing a carbon radical and an iodine atom upon cleavage, to form at least one polymer chain between said carbon radical and said iodine atom,
- wherein said monomer M.sub.2 has a larger addition reactivity with said carbon radical than said monomer M.sub.1, and a copolymerization reaction rate r.sub.2 of zero,
- wherein said monomer M.sub.1 has a copolymerization reaction rate r.sub.1 greater than 1 and less than 100, and
- wherein said iodine atom of said iodide compound may be withdrawn by a radical of said M.sub.2 monomer to form a terminal iodide bond between said M.sub.2 monomer radical and said iodine atom, said iodine atom of said terminal iodide bond having substantially the same transfer activity as said iodine atom when bonded to said iodide compound.
- 2. The process according to claim 1, wherein the copolymerization reaction ratio r.sub.1, of monomer M.sub.1 is larger than the reaction ratio r.sub.2 of monomer M.sub.2, and r.sub.1 is greater than 5 and less than 30, and r.sub.2 is zero.
- 3. The process according to claim 1, wherein said monomer M.sub.2 is an .alpha.-olefin.
- 4. The process according to claim 1, wherein said monomer M.sub.1 is a radically polymerizable unsaturated hydrocarbon.
- 5. The process according to claim 1, wherein said monomer M.sub.1 is an acrylic unsaturated compound.
- 6. The process according to claim 1, wherein said iodide compound is a fluorine-containing iodide compound.
- 7. The process according to claim 1, wherein said iodide compound is a low molecular weight perfluorinated alkyl iodide.
- 8. The process according to claim 1, wherein said iodide compound is an iodine-containing fluoropolymer.
- 9. The process according to claim 1, further comprising a step for converting a terminal carbon-iodine bond of the produced polymer to a carbon-hydrogen bond.
- 10. A process for preparing a polymer which comprises
- polymerizing at least one monomer M.sub.1, having a radically polymerizable unsaturated bond, in the presence of a monomer M.sub.2, which is different from said monomer M.sub.1, a radical generating source and an iodide compound having a cleavable carbon-iodine bond and capable of producing a carbon radical and an iodine atom upon cleavage, to form at least one polymer chain between said carbon radical and said iodine atom,
- wherein said monomer M.sub.2 has a larger addition reactivity with said carbon radical than said monomer M.sub.1 and a copolymerization reaction rate r.sub.2 of less than 2, and
- wherein said iodine atom of said iodide compound may be withdrawn by a radical of said M.sub.2 monomer to form a terminal iodide bond between said M.sub.2 monomer radical and said iodine atom, said iodine atom of said terminal iodide bond having substantially the same transfer activity as said iodine atom when bonded to said iodide compound.
