  • Methods of making cell carrier
    Patent number: 9453197
    Abstract: A method of making a carrier for growing cells, including providing a polymer film; embossing a patterned surface one or more sides of the polymer film with an embossing roller; generating a pattern of structured indentations on the polymer film; and discretizing the patterned polymer film into a plurality of portions. The embossing pattern generates relief features on the carrier surface. An alternative method of making a carrier is also provided, including extruding a polymer film; embossing a patterned surface on the polymer film with a roller; generating a pattern of structured indentations on the polymer film; imparting a surface treatment to the film; and discretizing the treated polymer film into a plurality of portions.

  • Melt-mixing thermoplastic and epoxy resin above Tg or Tm of thermoplastic with curing agent
    Patent number: 6197898
    Abstract: A process for preparing a polymer composition useful as a prepreg comprises (a) melt-mixing at least one thermoplastic polymer above the glass transition temperature or melt temperature of the thermoplastic polymer with either (i) an uncured epoxy resin or (ii) an epoxy curing agent or a catalyst; (b) melt-mixing above the glass transition temperature or melt temperature of the thermoplastic polymer, the other of (i) an uncured epoxy resin or (ii) an epoxy curing agent or a catalyst to form a substantially uncured but essentially curable and/or polymerizable composition; (c) optionally forming a shaped product from the melt-mixed composition of (b); and (d) fast-curing and/or fast-polymerizing the optionally formed shaped product.
