Abstract
Block copolymers include a poly β-methyl-δ-valerolactone (PMVL) block. The PMVL blocks can be formed from biosynthesized β-methyl-δ-valero lactone (MVL). The block copolymers can include hard blocks. The block copolymers can be thermoplastic elastomers.
Claims17
A block copolymer comprising:
- a poly(β-methyl-δ-valerolactone) (PMVL) block.
A method of forming a block copolymer, comprising:
- providing a living poly(β-methyl-δ-valerolactone) (PMVL) polymer or a telechelic PMVL block;
- and
- polymerizing one or more monomers from the living PMVL polymer or the telechelic PMVL block,
- wherein polymerizing the one or more monomers produces a polymer block having a glass transition temperature 10° C. or more greater than the glass transition temperature of the PMVL block.
