Abstract: A method of making a porous biodegradable polymer is disclosed, which comprises (a) placing a biodegradable polymer and a solvent in a chamber; (b) adding a supercritical fluid to the chamber and maintaining the chamber at a predetermined temperature for a sufficient period of time to allow the supercritical fluid to dissolve into the biodegradable polymer with the help of the solvent; and (c) venting the supercritical fluid and the solvent by reducing the pressure in the chamber, thereby obtaining a porous biodegradable polymer.

Abstract: The present invention relates to crosslinking of porous materials made of biodegradable polymers. The method comprises: (a) placing a porous biodegradable polymer in a chamber; (b) introducing a supercritical fluid containing a crosslinking agent into the chamber to effect crosslinking of the porous biodegradable polymer; and optionally (c) introducing a pure supercritical into the chamber to wash the crosslinked polymer until the crosslinking agent is substantially removed from the polymer.

Abstract: A molding machine for producing a continuous extrusion molding product with varying profile includes a die with an inlet for receiving molten material, a channel, an outlet, and shaping knives rotatable around axes non-parallel to the flow direction of the molten material between first and second operational positions. Shaping knives have molding surfaces and together define a first contour in the outlet when the shaping knives are in their first operational positions, and define a second contour in the outlet when the shaping knives are in their second operational positions. Shaping knives can be rotated around axes perpendicular or oblique to the flow direction of molten material.

Abstract: A biodegradable porous device for tissue engineering is disclosed, which comprises (A) a porous polymeric scaffold comprising a co-continuous phase of a first biodegradable polymer and a second biodegradable polymer which are incompatible with each other, wherein the first biodegradable polymer contains a continuous network of large, interconnected pores, and the second biodegradable polymer contains small, partially interconnected pores; (B) a biodegradable polymer fiber dispersed in, and compatible with the matrix of the first biodegradable polymer; and optionally (C) an active ingredient provided in the polymeric scaffold.

Abstract: A resin composition with a low dielectric constant comprises: (a) a functionalized cyclic olefin copolymer; (b) a mixture of epoxy resins; and (c) a curing agent. A laminate and a resin coated clad made of the resin composition exhibit reduced dielectric constants of 3.3 and 2.9 at 1 GHz, respectively.

Abstract: The present invention provides a method and apparatus for producing a crosslinked foamed article. Such a method comprises the steps of: (a) uniformly mixing at least one crosslinkable resin, at least one crosslinking agent, at least one foaming agent, and some additives into a resin composition; (b) extruding the resin composition through a die into an extrudate of a predetermined shape; and (c) heating the extrudate to a temperature sufficient to cause crosslinking and foaming of the crosslinkable resin while being driven by a driving device to move in the extruding direction, thereby obtaining a crosslinked foamed article. By means of the present invention, the resin extrudate can progress smoothly through the heater or the mold.
