Abstract: A process of having a microporous multiply sheet product which is capable of becoming non-porous at a predetermined elevated transformation temperature is formed by first forming a non-porous, multiply initial sheet product having at least one first ply and at least one second ply, each with its own viscosity profile. The initial sheet product is then stretched and annealed to impart porosity to the sheet product.

Abstract: A method for preparing a microporous polyolefin shaped article which includes the steps of (1) melt blending a polyolefin with an additive which is miscible with the polymer at the melt temperature of the blend but which phase separates on cooling to form a solution; (2) forming a shaped article from the solution; (3) cooling the shaped article by use of a patterned chill roll to provide areas on the surface of the article where the polymer mixture does not contact the chill roll; and (4) (a) removing at least a substantial portion of the compatible liquid; or (b) stretching the article in at least one direction sufficient to permanently attenuate the article and effect orientation of the polymer; or (c) a combination of (a) and (b) to form a microporous polyolefin shaped article. The article is of substantially uniform thickness and has a patterned surface. The patterned surface provides substantially skinless areas having high microporosity and skinned areas or reduced porosity.

Abstract: Microporous membranes and methods for producing such membranes from ultrahigh molecular weight polyethylene are described. The method employs extrusion of a solution of UHMW-PE and porogen through a forming die followed by thermal phase separation of polymer and porogen. Microporous structures are created by removing porogen. Microporous membranes produced include membranes with good permeability to air and water making them particularly useful as filtration media and water-resistance breathable membranes.
