An ordered structured organic film comprising a plurality of segments and a plurality of linkers arranged as a covalent organic framework, wherein the structured organic film may be a multi-segment thick structured organic film.

The invention relates to a method for transporting foamed thermoplastic polymer particles (3) from a container (5, 9) through at least one pipe (7, 11), wherein, for transporting the foamed thermoplastic polymer particles (3), a gas stream is applied through the pipe (7, 11). The foamed thermoplastic polymer particles (3) are wetted with a water comprising lubricant.

A polyurethane composition, comprising (A) an isocyanate compound and (B) a polyol blend of three polyether polyols having particularly designed formulation and OH functionality, is provided. The viscoelastic polyurethane foam prepared by using said polyurethane composition exhibits tailored viscoelastic properties and superior aesthetic appearance.

A resin composition, including resin and imidazole, is provided. The resin includes cyanate ester resin and bismaleimide resin, and the imidazole does not have acidic hydrogen.

A method of producing olefinic and aromatic hydrocarbons from waste plastics comprising feeding a mixture of plastics along with the products of the oxidation of light hydrocarbons to a process in which the feed mixture is catalytically pyrolyzed to produce olefins and aromatics.

The present invention relates to novel anisotropic composite materials and processes for production thereof. The composite materials are based on the crosslinking of polyisocyanates and feature good weathering stability.

In one embodiment, a mixture includes a polyfunctional monomer having at least one functional group amenable to polymerization, a porogen, and a polymerization initiator. In another embodiment, a product includes a porous three-dimensional structure formed by additive manufacturing, where the porous three-dimensional structure has ligaments arranged in a geometric pattern, the ligaments defining pores therebetween. The pores have an average diameter greater than about 10 microns, where an average length scale of the ligaments is greater than 100 nanometers. The ligaments are nanoporous, where at least 80% of a volume measured according to outer dimensions of the porous three-dimensional structure corresponds to the pores.

Systems and methods for producing aerogel materials are generally described. In certain cases, the methods do not require supercritical drying as part of the manufacturing process. In some cases, certain combinations of materials, solvents, and/or processing steps may be synergistically employed so as to enable manufacture of large (e.g., meter-scale), substantially crack free, and/or mechanically strong aerogel materials.
