  • Organic polymers modified with silicone materials
    Patent number: 5708084
    Abstract: There is disclosed a polyolefin composition which can be extruded at relatively high rates to provide extrudate having improved hydrophobicity, said composition comprising (A) 100 parts by weight of a thermoplastic resin; and (B) at least 1 part by weight of an interactive diorganopolysiloxane process aid, said diorganopolysiloxane having a number average molecular weight of at least 10,000.
    Type: Grant
    Filed: August 28, 1996
    Date of Patent: January 13, 1998
    Assignee: Dow Corning Corporation
    Inventors: Dale Earl Hauenstein, Caibao Qian, David Joseph Romenesko
  • Method of preparing solventless, thermoplastic silicone pellets and the pellets so-produced
    Patent number: 5708098
    Abstract: Solventless, thermoplastic silicone pellets are prepared blending silicone resins (A) of the MQ-type and with predominantly linear silicone fluids (B), such as polydimethylsiloxane liquids and gums, to substantially homogeneity. The blends are heated to a predetermined compression-forming temperature, compression-formed to a densified mass and shaped into a pellet form. The composition of the pellets is balanced such that the pellets exhibit plastic flow at the predetermined compression-forming temperature and resist agglomeration at temperatures at or below a predetermined maximum storage temperature.

  • Low density polyethylene modified with silicone materials
    Patent number: 5708085
    Abstract: There is disclosed a polyolefin composition which can be extruded at relatively high rates to provide extrudate having improved hydrophobicity, said composition comprising(A) 100 parts by weight of a polythylene resin; and(B) 1 to 5 parts by weight of an interactive diorganopolysiloxane process aid, said diorganopolysiloxane having a number average molecular weight of at least 10,000. In particularly preferred embodiments, an interactive diorganopolysiloxane in combination with a low density polyethylene is used as a process aid for linear low density polyethylene.
