  • Semi-crystalline thermoplastic polymers and articles manufactured therefrom
    Patent number: 9284388
    Abstract: Disclosed herein is a method comprising masticating a molten polymer; where the polymer is semicrystalline polymer prior to melting; where the masticating polymer is conducted at an elevated temperature of Tm?15K to Tm+90K; where Tm is the crystalline melting point of the polymer; masticating the molten polymer while it is cooled from the elevated temperature to a temperature of Ta; where Ta is a temperature that is greater than Tc?10K, where Tc is the crystallization temperature of the polymer; and masticating the polymer at the temperature of Ta for a time period of 0.1 to 50 minutes.
    Type: Grant
    Filed: April 30, 2015
    Date of Patent: March 15, 2016
    Assignee: THE UNIVERSITY OF MASSACHUSETTS
    Inventors: Alan J. Lesser, Brian M. Cromer, Edward B. Coughlin

  • Polymerization of olefins
    Publication number: 20010031845
    Abstract: Olefins such as ethylene and propylene may be polymerized by using as catalysts novel selected transition metal complexes of bis(carboximidamidatonates) in which the carboximidamidatonate groups are connected together through covalent bonds by a bridging group. The resulting polymers are useful as molding and extrusion resins.
