  • Method for reducing plate-out of solid phosphites in polymers
    Patent number: 8445567
    Abstract: A process is described which reduces the amount of bloom and/or plate-out of phosphite antioxidants during polymer processing by the addition of at least one polyethylene glycol (or blends thereof) or polycaprolactones (or blends thereof) having an average molecular weight of approximately 1,000 to 20,000, most preferably between 4,000 to 10,000.
    Type: Grant
    Filed: February 22, 2010
    Date of Patent: May 21, 2013
    Assignee: Dover Chemical Corporation
    Inventors: Donald Stevenson, Michael Jakupca, Nina Bersaglini
  • Mixed alkyl-alkylaryl-phenyl phosphite polymer additive
    Patent number: 8258215
    Abstract: A process to stabilize a polymer is described utilizing the step of adding a phosphite reaction product of a triphenyl phosphite or lower molecular weight trialkyl phosphite (e.g., trimethyl phosphite) or triaryl phosphite, with from approximately 1 to 2 moles of preferably a paracumyl phenol, and with from approximately 1 to 2 moles of at least C12-20 carbon alkyl or C12-20 alkenyl alcohol.
    Type: Grant
    Filed: February 5, 2010
    Date of Patent: September 4, 2012
    Assignee: Dover Chemical Corporation
