  • Composite polymer modifiers
    Patent number: 9085679
    Abstract: The invention relates to composite polymer modifiers for thermo-plastic resins, and especially for polyvinyl chloride (PVC). The composite modifier is an intimate blend of mineral filler and polymeric process aid, which is formed by the co-powderization of aqueous emulsions, suspensions or slurries of one or more mineral filler(s) and process aid(s). The resulting composite modifier provides more effective modification of the thermoplastic resin than by the use of the dried components formed separately. The composite modifier may also contain other co-powderized components such as impact modifiers, for additional benefits.

  • Random copolymer oil return agents
    Patent number: 9062236
    Abstract: The present invention relates to polymeric oil-return agents which solubilize or disperse mineral oil and/or synthetic oil lubricants with hydrofluorocarbon, hydrochlorofluorocarbon, and hydrofluoroolefin-based refrigerants and refrigerant compositions containing them. The polymeric oil-return agents are random copolymers containing less than about 30 wt % fluorine and produced from at least one monomer providing compatibility with the oil phase and at least one monomer providing compatibility with the refrigerant phase. The polymeric oil-return agents provide for more efficient return of mineral oil and/or synthetic oil lubricants from non-compressor zones back to a compressor zone in a refrigeration system.

  • Epoxidized composition and methods for making the same
    Patent number: 9034965
    Abstract: The invention relates to an epoxidized composition and a process for producing the same. The epoxidized composition is useful as a plasticizer for thermoplastics such as polyvinyl chloride (PVC) and other polymers.
