摘要： 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.

摘要： A method for improving consolidation of powder resin is provided. The method broadly includes the steps of: (1) sorting particles of the powder resin according to their diameter; (2) combining the sorted particles having a first diameter D1 with the sorted particles having a second diameter D2 so as to form a particle mixture; (3) applying a vibration to the particle mixture; (4) heating the particle mixture; and (5) delivering the particle mixture through a nozzle or into a mold. The particle diameters D1 and D2 are chosen so that once combined there is optimal close packing of the three-dimensional spaces between the powder resin particles.
