The present disclosure provides device having a reaction vessel with one or more permeable membranes disposed therein that separate the reaction vessel into at least a first portion and a second portion. The one or more membranes permit first reactants from a first solution in the first portion or reactants from a second solution in the second portion to seep or percolate to a reaction zone proximate a surface of the one or more membranes. A reaction of the first and second reactants forms a two-dimensional polymer film material. A roller located inside of the reaction vessel draws the two-dimensional polymer film material reaction out of the reaction zone.

Method for producing a three-dimensional motor vehicle interior element through which light can shine, and a motor vehicle interior element

A method for producing a three-dimensional motor vehicle interior element through which light can shine and which has an observer-side surface is produced in two steps. In a first step a three-dimensional transparent substrate is produced from a cross-linked polymer. In a second step the substrate is provided on an observer-side surface of the substrate with a coloring through which light can shine, at least in a subregion.

Process for the preparation of a reinforced polyamide by extrusion

The present invention relates to a process for the production of a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2) and a third mixture (M3) are added into the extruder, and subsequently at least one carbon material is added to obtain a carbon containing polymerizable mixture (cpM) in the extruder. This carbon containing polymerizable mixture (cpM) is polymerized and subsequently devolatilized to obtain the reinforced polyamide (rP). Furthermore, the present invention relates to the reinforced polyamide (rP) obtainable by the inventive process.

METHOD AND INJECTION MOLDING SYSTEM FOR THE DIRECT SOLING OF A MULTILAYERED SHOE SOLE
20220273071 · 2022-09-01 ·

Some embodiments relate to a method for the direct soling of a multilayered shoe sole. The method can provide two distinct sets of mold frames for a first and a second shoe sole layer and a distinct order for the soling of the layers. In contrast to art traditional approaches, a first layer (e.g. a midsole) is first soled to an upper in a first mold frame and subsequently a second layer (e.g. an outer sole) is soled onto said first layer in a second mold frame. The method can allows for an increased design flexibility and the inclusion of additional functional or aesthetic features, such as air pockets, undercuts, toe caps or running sole tips previously not possible with direct soling processes. Some embodiments relate to an injection molding system equipped and configured for carrying out the method.

TUNABLE, CONTROLLED-RELEASE, URETHANE-CONTAINING ELASTOMERS AND PROCESSES OF FORMING THE SAME

A process forms an implantable product including poly(glycerol sebacate) urethane (PGSU) loaded with an active pharmaceutical ingredient (API). The process includes homogeneously mixing a flowable poly(glycerol sebacate) (PGS) resin with the API and a catalyst to form a resin blend. The process also includes homogeneously combining the resin blend with an isocyanate to form a reaction mixture and injecting the reaction mixture to form the PGSU loaded with the API. An implantable product includes a PGSU loaded with an API. In some embodiments, the implantable product includes at least 40% w/w of the API, and the implantable product releases the API by surface degradation of the PGSU at a predetermined release rate for at least three months under physiological conditions. In some embodiments, the PGSU is formed from a PGS reacted with an isocyanate at an isocyanate-to-hydroxyl stoichiometric (crosslinking) ratio in the range of 1:0.25 to 1:1.25.
