Abstract: The present invention relates to a method and composition for the cryopreservation of adipose tissue with the intention to use this tissue in the culturing of stem and/or progenitor cells. The method uses a specific cryoprotection medium to prevent damage of the original tissue during the cryopreservation while still maintaining a high viability of the stem and/or progenitor cells obtained from the cryopreserved adipose tissue. Furthermore the cryoprotection medium of the present invention does not contain any kind of xenogeneic sera, a critical factor since it is the intention of that the cryopreserved tissue is used for obtaining stem and/or progenitor cells that can be used in medicine. The cryoprotection medium is characterized in that it is a solution of physiological water comprising glycerol and sucrose and/or trehalose and optionally serum albumin.

Abstract: The invention relates to non cross-linked modifiers for thermoplastic alloys comprising from 20 to 80% by weight based on the modifier of an interpolymer of ethylene and an alpha-olefin having from 4 to 12 carbon atoms grafted with an acid functionality, preferably maleic anhydride, having a Melt Index of from 0.3 to 100 and a density of 0.85 to 0.91 prior to being grafted and from 80 to 20% by weight of an ungrafted diene containing interpolymer derived from ethylene and an alpha-olefin having from 3 to 12 carbon atoms and an amount of a cross-linking component effective to provide cross-linking during subsequent melt blending with a condensation polymer having a melting point of at least 150° C.

Abstract: The invention relates to thermoplastic compositions in which (A) an isotactic polypropylene, optionally containing comonomer, with a melting point of at least 110° C. and (B) a polyamide, (A) and (B) constituting at least 70 wt %, are blended with (C) at least 2 wt % of a grafted functionalized propylene-based elastomer having isotactic crystallinity and containing at least 0.25 wt % of MAH-derived units based on the total weight of (C). Optionally (D) an ungrafted polyolefin may be added with a melting point of less than 100° C., (C) and (D) combined being at least 8 wt % and the wt % of (A), (B), (C) and (D) being calculated on the basis of the total polymer weight of the thermoplastic composition.

Abstract: Resins having a softening point from 10.degree. C. to 120.degree. C. especially 10.degree. C. to 80.degree. C. being a copolymer of a feed which is predominantly C.sub.5 olefines and diolefines and 10 to 60 wt. % of one or more monovinyl aromatic compounds are used as a tackifier for acrylic polymers or copolymers particularly in aqueous based pressure sensitive adhesives.

Abstract: Resin emulsions are prepared by forming an emulsion of an aqueous solution of an unsaturated material reactive with the resin in the liquid resin, causing the material and the resin to react and adding sufficient water to invert the emulsion to form an emulsion of the reacted resin in water to produce emulsions with improved mechanical stability useful as tackifiers in water-based pressure-sensitive adhesive coating materials in high speed coating lines giving reduced deposits and extended coating times.
