The invention relates to a method for producing thermoplastic fibre composites made from a thermoplastic matrix (M) comprising a thermoplastic moulding compound (A) and reinforcing fibres (B). Said method has technical advantages when it comprises the following steps: i) a flat structure (F) made of reinforcing fibres (B) is provided, ii) the flat structure (F) is introduced into a matrix M, iii) functional groups of the matrix are reacted with polar groups of the reinforcing fibres (B), iv) the fibre composite materials is consolidated.

An elastomeric composition and method incorporating a hydrocarbon polymer modifier with improved permanence. The composition comprises elastomer, filler and silane-functionalized hydrocarbon polymer modifier (Si-HPM) made in a pre-reaction adapted to couple the Si-HPM to the elastomer, filler or both, wherein the Si-HPM comprises an interpolymer of monomers chosen from piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof.

The present invention relates to the technical field of copper clad laminates and relates to a resin composition and a pre-preg and a laminate using the composition. The resin composition comprises: (A) a prepolymer of vinyl thermosetting polyphenylene ether and a bifunctional maleimide or a multifunctional maleimide; and, (B) a polyolefin resin. The present invention, by employing the prepolymer of vinyl thermosetting polyphenylene ether and the bifunctional maleimide or the multifunctional maleimide, solves the problem of incompatibility of the bifunctional maleimide or the multifunctional maleimide with the vinyl thermosetting polyphenylene ether and the polyolefin resin. An aqueous glue solution so mixed is uniform and consistent, the prepreg has a uniform expression, and a substrate resin area is free of a phase-separation problem. In addition, the maleimide employed is either the bifunctional maleimide or the multifunctional maleimide, relative to a monofunctional maleimide, a substrate so prepared is provided with increased heat resistance, a reduced thermal expansion coefficient, extended thermal stratification time, and increased thermal decomposition temperature.

Provided is a cushion partially or entirely composed of a foam, wherein the foam is composed of: a hydrocarbon-based oil including ethylene and -olefin as constituent units; and a polymer composition including one or a plurality of polymers.

Disclosed herein are methods of preparing a composite, comprising mixing a solid elastomer, a wet filler, and a resin. Single-stage or multi-stage mixing methods can be used. Also disclosed are composite comprising the filler dispersed in the elastomer at a loading of at least 20 phr, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.

Provided are porogen compositions and methods of using such porogen compositions in the manufacture of porous materials, for example, porous silicone elastomers.
