Abstract
Methods of polymerizing a diene to produce a polydiene, the method comprising (i) melting a diene to produce a neat liquid; and (ii) irradiating the melted polydiene with ultraviolet (UV) light to produce a polymer; wherein the melting and irradiating are performed substantially in the absence of solvent or catalyst.

A method of polymerizing a polydiene comprising
- (i) melting a diene to produce a melted diene;
- and
- (ii) irradiating the melted diene with ultraviolet (UV) light to produce a polymer;
- wherein the melting and irradiating are performed substantially in the absence of solvent or catalyst.

A method of producing a polymer comprising:
- (i) reacting muconic acid with a compound of the formula R—OH to form a dialkyl muconate, wherein R is C1-C12 alkyl;
- (ii) melting the dialkyl muconate to produce a neat liquid;
- (iii) irradiating the melted dialkyl muconate with ultraviolet (UV) light to produce a polymer;
- and
- (iv) mixing styrene into the polymer in the absence of UV light to produce a triblock copolymer.
