Abstract
A new thermoplastic homopolymer of o-cresol which is a poly(2-methylphenylene oxide) having a high molecular weight distribution is described. The polymer is prepared using a 2 and/or 6 substituted pyridine catalyst to the molecular weight distribution. The homopolymer can be blended with other thermoplastic polymers. The homopolymer is rapidly biodegraded, particularly in soil containing soil microorganisms.
