Disclosed herein is a method for effecting atom or group transfer polymerization comprising polymerizing one or more radically-polymerizable monomers in the presence of a system comprising an electrically active micro-organism, a transition metal catalyst, one or more radically-polymerizable monomers, and a radical initiator. Micro-organism respiratory electron flux is harnessed to control the performance of a metal-catalyzed polymerization. The bacterial electron transport pathways of the electroactive micro-organisms can be engineered to tune and adapt various function of the electroactive micro-organism and its role in polymerization. Polymerization may be accomplished under aerobic or anaerobic conditions. Freshly cultured micro-organisms or lyophilized micro-organisms may be used to direct polymerization.

Metabolic control over organometallic catalysts using electroactive bacteria

Disclosed herein are catalyst systems useful for a wide range of ring opening polymerization processes. Epoxides, oxetanes, lactones and cyclic carbonates are all suitable substrates for the ring opening polymerization.

Catalysts for ring opening polymerization

The present disclosure relates to copolymers and methods for copolymer preparation. Disclosed herein are high molecular weight copolymers of lactones and epoxides and methods for their synthesis.

Lactone-epoxide statistical copolymers

The present invention provides for a polymer formed by reacting a first reactant polymer, or a mixture of first reactant polymers comprising different chemical structures, comprising a substituent comprising two or more nitrogen atoms (or a functional group/sidechain comprising a two or more nitrogen atoms) with a second reactant polymer, or a mixture of second reactant polymers comprising different chemical structures, comprising a halogen substituent (or a functional group/sidechain comprising a halogen).

Polymer useful for an ion exchange membrane

A polymer electrolyte composition including a metal salt and at least one polymer comprising a poly(glycidyl ether), where the at least one polymer is amorphous at ambient temperature. The poly(glycidyl ether) polymer can be a blend of poly(glycidyl ether) polymers, can be a poly(glycidyl ether) polymer blended with a mechanically strong solid polymer, and can be a block of a block copolymer that also includes a polymer block forming a mechanically strong solid polymer.
