1. A method of synthesizing metal-free, high molecular weight polymers with low polydispersity, comprising the steps of:

  • a) providing a mixture of an alcohol and a solvent;

    b) adding t-BuP4 to the mixture to make a metal-free initiator;

    c) adding monomers to the initiator;

    d) allowing the monomers and the initiator to react to form a metal-free, high molecular weight polymers with a polydispersity less than 1.5;

    wherein the alcohol is selected from the group consisting of bisphenol A, 2,5-dimethyl-2,5-hexanediol, phenol, and t-butyl alcohol.
