Patent number: 9586355Abstract: A dynamically vulcanized alloy containing an elastomer and a thermoplastic resin is prepared by a process wherein supercritical fluid is injected into the thermoplastic elastomeric material as the material is mixed in an extruder. The material is mixed under conditions such that the thermoplastic elastomeric material is dynamically vulcanized wherein the elastomer forms a discontinuous dispersed of small particles in a continuous phase of the thermoplastic resin. The DVA material may then be directly formed into film or sheets by the use of at least one set of rolls located adjacent to the extruder outlet.Type: GrantFiled: March 11, 2011Date of Patent: March 7, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Jianya John Cheng, Prashant Arun Bhadane, Basil D.

Patent number: 8257624Abstract: A method for making a porous material, includes melt-blending two or more non-miscible polymers to obtain a co-continuous melt, solidifying the melt to obtain a solid mass consisting of two co-continuous polymer phases, and selectively extracting one of the co-continuous phases thereby creating within the solid mass an essentially continuous pore network having an internal surface. The method further includes replicating the internal surface of the pore network within the solid mass by coating the internal surface with successive layers of materials, and selectively extracting the solid mass without extracting the layers of materials, to thereby yield the product porous material, formed of the layers of materials. The material has a void fraction higher than about 75%, and mainly having essentially fully interconnected sheath-like non-spherical pores and essentially non-fibrous walls.Type: GrantFiled: November 14, 2006Date of Patent: September 4, 2012Inventors: Basil D.

Patent number: 8007823Abstract: The present invention relates to a highly controlled method of preparation of a microporous biodegradable polymeric article. Firstly, at least one biodegradable polymer A, one polymer B, biodegradable or not, partially or totally immiscible with A, and a compatibilizer C for A and B are selected. Secondly, the selected polymers are melt-blended, thereby preparing a polymer blend, wherein said polymers A and B have an essentially continuous morphology. Thirdly, after cooling, polymer B and compatibilizer C are selectively extracted from the polymer blend by dissolution in a solvent that is a non-solvent of polymer A. The resulting polymeric article has an essentially continuous porosity with a void volume between 10 and 90% and a unimodal diameter distribution set to a predefined unimodal peak location. It can be used in tissue engineering, for controlled release applications or as an implantable medical device.Type: GrantFiled: April 2, 2004Date of Patent: August 30, 2011Assignee: Corporation de l'Ecole Polytechnique de MontrealInventors: Basil D.
