  • Process for making gray expanded polystyrene
    Patent number: 10544277
    Abstract: Gray expanded polystyrene achieving target molecular weight, bead size, bead distribution, and cell structure may be reproducibly prepared by suspension polymerization by introducing to the suspension polymerization an additive that is carbon black and/or graphite only after approximately 20 to 60 wt % of the styrene monomer has been converted to polystyrene. Introducing the additive at this point slows the polymerization rate, such as for an optimized period of time to allow for the droplet size to equilibrate to the desired target range. In one nonlimiting embodiment, the styrene polymerization rate has about 35 wt % to about 60 wt % styrene monomer remaining after about 3 hours from the beginning of polymerizing.
    Type: Grant

  • Color development of carbon black in expanded polystyrene
    Patent number: 10414895
    Abstract: When long chain primary alcohols are into expanded polystyrene (EPS) containing an additive such as carbon black or graphite to give gray EPS, the long chain primary alcohols act as color enhancing agents and generate a darker color as compared with an otherwise identical gray EPS absent the additive.
