Abstract: A thermoplastic biobased material-containing composition comprising chemically-modified feathers and/or dried distillers grains and a process for forming the thermoplastic biobased material-containing composition. More specifically, the thermoplastic biobased material-containing composition comprises one or more of the following chemically-modified biobased materials: (a) acylated biobased material having a % Acyl Content that is at least 3% and a % Weight Gain that is at least 1%, and; (b) etherified biobased material having a % Weight Gain that is at least 2%; and (c) graft polymerized biobased material having a % Monomer Conversion that is at least 40%, a % Grafting Efficiency that is at least 30%, and a % Grafting that is at least 10%.

Abstract: The present in invention relates to a method for the separation of living cells from a mixture of dead and living cells which optionally can also possibly contain cell fragments.

Abstract: Disclosed is a method for modifying naturally occuring biocompatible biopolymers of plant and animal origin by subjecting same to ionizing radiation in the presence of a mediating gas, typically acetylene to enable one to selectively enhance and modify one or more of the physiochemical propserties of the starting materials which have a wide range of uses in medicine, food technology and other industrial applications. Notwithstanding the modifications, the biocompatibility of the biopolymer remains unchanged and no new or additional functional groups are introduced into the starting biopolymer.

Abstract: The present invention relates to a biocompatible collagenous material which is non-toxic and biodegradable in less than one month, preferably in less than one week. This material comprises collagen and at least one hydrophilic macromolecular additive which is chemically non-reactive towards the collagen, with the collagen having at least partially lost its helical structure and being crosslinked. The invention also relates to a process for obtaining such a material. The collagenous material according to the invention is used, in particular, for preventing post-operative adhesions.

Abstract: The invention relates to the chemical bonding of a polymer/or polymers onto non-metallic substrates such as cellophane by ultrasonic techniques. The cellophane film is preactivated by contacting with silver nitrate solution followed by treatment with potassium hydroxide solution whereby particles of silver and silver oxide are uniformly distributed, in situ, over the surface of cellophane film. The pretreated cellophane film when contacted with grafting solution, that contains monomers, prepolymers, catalyst, graft initiator and other ingredients of the composition, which is being agitated with ultrasonic energy results in polymerization of monomer/prepolymer onto the surface of the cellophane film.
