    摘要： The invention relates to a process for the preparation of porous polyolefin particles, which process comprises the following steps: 1) dissolution of at least one crystallizable polyolefin in a solvent, which results in a solution being formed which comprises 0.1-50 wt.% polyolefin, and the initial polyolefin solution formed containing between 5 ppm and 20 wt.% of nucleating agent; 2) dispersion of the resulting polyolefin solution in a non-solvent, at a temperature that is higher than the crystallization temperature of the polyolefin in the polyolefin solution, upon which a multiphase system is formed; 3) cooling of the multiphase system, with simultaneous stirring, the cooling rate being between 0.05 and 10 °C/min, down to a temperature which is below the crystallization temperature of the polyolefin in the polyolefin solution, so that strong, polyolefin-containing particles are formed; 4) separation of the polyolefin-containing particles from the liquid(s); 5) drying of the polyolefin-containing particles at a temperature that is below the crystallization temperature of the polyolefin in the initial polyolefin solution.

    摘要： The present invention provides a microporous material or a membrane in which the membrane includes an azlactone moiety which is blended with or grafted to a thermoplastic polymer to provide a porous material having an internal structure characterized by a multiplicity of spaced, randomly disposed, non-uniform shaped, equiaxed particles of the polyazlactone polymer/thermoplastic polymer blends or the azlactone-graft copolymer. Each of the adjacent particles throughout the material are separated from one another to provide said material with a network of interconnected micropores and each of the particles are connected to each other by a plurality of fibrils. In addition to unmodified azlactone membranes, membranes which have been modified by subsequent reaction of the azlactone moiety with a suitable nucleophile are also included within the scope of the present invention. Preferred nucleophiles capable of reacting with an azlactone membrane of this invention include biologically significant nucleophiles such as amines, thiols and alcohols as well as amino acids, nucleic acids and proteins.

    摘要： A membrane or laminate (10) consisting essentially of microporous polymerized material (12) consisting essentially of a precursor material which forms a homogenous solution with a liquid vehicle and is 1) rapidly polymerizable under ultraviolet or electron beam irradiation to a polymerized material, which is insoluble and nondispersible in the liquid vehicle, and 2) selected from the group consisting of organic monomers, organic oligomers, and mixtures thereof which are soluble in the liquid vehicle, the liquid vehicle being inert relative to the precursor material and optionally a support material (14) laminated directly to the microporous material. The precursor microporous material may include a hydrophobic monomer. The instant invention further provides a method for manufacturing the fluid permeable microporous membrane laminate (10) including the steps of mixing the precursor material into the liquid vehicle, forming the composition into a thin liquid layer, applying a support material (14) into intimate contact with the liquid layer, exposing the combined liquid layer and support material (14) to ultraviolet or electron beam irradiation to finally cure the liquid layer and form a laminate with the support material 14, and removing the liquid vehicle from the laminate (10).

    摘要： A method of making a microporous sheet is provided which comprises the steps of melt blending crystallizable thermoplastic polymer with a compound which is miscible with the thermoplastic polymer at the polymer melting temperature but immiscible on cooling below the polymer melting temperature, forming a sheet of the melt blend, cooling the sheet to a temperature at which the compound becomes immiscible with the polymer to cause phase separation to occur between the thermoplastic polymer and the compound to provide a sheet comprising a first phase comprising particles of thermoplastic polymer in a second phase of said compound, orienting the film in at least one direction to provide a network of interconnected micropores throughout the sheet. The microporous sheet comprises about 30 to 80 parts by weight crystallizable thermoplastic polymer and correspondingly about 70 to 20 pans by weight of the compound. The oriented sheet has a microporous structure characterized by a multiplicity of spaced randomly dispersed, equiaxed, non-uniform shaped, non-porous particles of the thermoplastic polymer which are coated with the compound. Adjacent thermoplastic particles within the sheet are connected to each other by a plurality of fibrils consisting of the thermoplastic polymer. The fibrils radiate in three dimensions from each particle. The compound may be removed from the sheet. e.g., by solvent extraction.
