Claims5
A method of making a thermoplastic polymer block suitable for polymerization with one or more other, different polymer blocks or suitable for use as a thermoplastic elastomer without combination with one or more other, different monomers or polymer blocks, comprising:
- providing a polymerization macroinitiator in the form of at least one halogenated polymer oil selected from the group consisting of:
- a halogenated heat-bodied, renewable source-derived oil;
- a halogenated blown, renewable source-derived oil;
- a halogenated, renewable source-derived copolymer oil;
- a halogenated hydrogenated heat-bodied, renewable source-derived oil;
- a halogenated hydrogenated blown, renewable source-derived oil;
- a halogenated hydrogenated renewable source-derived copolymer oil;
- and combinations of any thereof;
- combining the polymerization macroinitiator with a suitable atom transfer radical polymerization catalyst in the form of a transition metal halide and with a solvent for the polymerization macroinitiator, but in the absence of any atom transfer radical polymerization initiator other than a polymerization macroinitiator as described above;
- and
- in solution, causing an atom transfer radical polymerization of the polymerization macroinitiator with itself via one or more sites wherein a fatty acid double bond of the oil has been halogenated, a free hydroxyl group of the oil has been halogenated or an alpha carbon of a fatty acid moiety of the oil has been halogenated and via residual unsaturation in the polymerization macroinitiator.
A method of making a copolymer, comprising:
- combining:
- a) a polymerization macroinitiator in the form of at least one halogenated polymer oil selected from the group consisting of:
- a halogenated heat-bodied, renewable source-derived oil;
- a halogenated blown, renewable source-derived oil;
- a halogenated, renewable source-derived copolymer oil;
- a halogenated hydrogenated heat-bodied, renewable source-derived oil;
- a halogenated hydrogenated blown, renewable source-derived oil;
- a halogenated hydrogenated renewable source-derived copolymer oil;
- and combinations of any thereof and
- b) a radically polymerizable monomer with
- a suitable atom transfer radical polymerization catalyst in the form of a transition metal halide and with a solvent for a) and b) but in the absence of any other atom transfer radical polymerization initiator, to form a solution comprised of a) and b) with the atom transfer radical polymerization catalyst;
- and
- causing an atom transfer radical polymerization to take place in the solution.
A method of making a copolymer, comprising:
- combining:
- a) a polymerization macroinitiator in the form of at least one halogenated polymer oil selected from the group consisting of:
- a halogenated heat-bodied, renewable source-derived oil;
- a halogenated blown, renewable source-derived oil;
- a halogenated, renewable source-derived copolymer oil;
- a halogenated hydrogenated heat-bodied, renewable source-derived oil;
- a halogenated hydrogenated blown, renewable source-derived oil;
- a halogenated hydrogenated renewable source-derived copolymer oil;
- and combinations of any thereof and
- b) a polymerized linear-chain or branched-chain polymer block comprised of repeating units of a radically polymerizable monomer or of units of two or more radically polymerizable monomers
- with
- a suitable atom transfer radical polymerization catalyst in the form of a transition metal halide and with a solvent for a) and b), but in the absence of any other atom transfer radical polymerization initiator, to form a solution comprised of a) and b) with the atom transfer radical polymerization catalyst;
- and
- causing an atom transfer radical polymerization to take place in the solution.
