Abstract
Compositions comprising renewable source derived polymer oil polymerization macroinitiators and multiblock polymer compositions derived therefrom by atom transfer radical polymerization are disclosed. Hard, glossy multiblock copolymers, thermoset multiblock copolymers, thermoplastic block copolymer elastomers, and methods of making and using these types of materials are disclosed.
Claims2
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.
