The present invention relates to a process for the production of polyacrylonitrile by polymerisation of a reaction mixture comprising acrylonitrile in a solution where the solvent is a eutectic system comprising a quaternary ammonium compound and a hydrogen donor. Such process allows for the production of a polyacrylonitrile having a desirably high molecular weight, whilst polymerisation time is reduced, and where the solvents are environmentally benign, biodegradable and may be reused in the polymerisation process.

Process for the production of polyacrylonitrile

The present invention relates to a polymer composition comprising&#x2014;polycarbonate; -(meth)acrylic polymer; and-&#x2265;1.0 and &#x2264;10.0 wt % polyalkylene glycol with regard to the total weight of the polymer composition. Such polymer composition can be produced by for example a conventional compounding process using melt extrusion, wherein polycarbonates and PMMA can be converted into a polymer composition having the desired properties without need for using dedicated process equipment.

Composition comprising a (meth)acrylic polymer and polycarbonate

The present invention relates to a process for the production of an ethylene-propylene-diene terpolymer (EPDM) composition in a reaction vessel comprising the following steps in this order: (a) supplying a quantity of a first composition comprising an ethylene copolymer or a propylene copolymer and a first peroxide to the reaction vessel; (b) supplying a quantity of a second composition comprising EPDM and a second peroxide to the reaction vessel; or (a) supplying a quantity of a second composition comprising EPDM and a second peroxide to the reaction vessel; (b) supplying a quantity of a first composition comprising an ethylene copolymer or a propylene copolymer and a first peroxide to the reaction vessel; and (c) exposing the contents of the reaction vessel under stirring to a temperature of 100-200&#xb0; C.; wherein the ethylene copolymer is a copolymer comprising polymeric units derived from ethylene and polymeric units derived from a mono-olefinic compound comprising 3 to 10 carbon atoms, and wherein the propylene copolymer is a copolymer comprising polymeric units derived from propylene and polymeric units derived from a mono-olefinic compound comprising 2 carbon atoms or 4-10 carbon atoms. Such process allows for the production of an oil-extended EPDM composition having a certain high Mooney viscosity whilst still using an EPDM as obtained from the polymerisation process having a relatively moderate Mooney viscosity.

Reinforced polyimide compositions that include a reinforcing filler and a polyamide flow promoter improve flow promotion while maintaining other mechanical, thermal, flame and/or electrical properties of the compositions. The compositions may include an inorganic or organic reinforcing filler, a polyimide resin such as polyetherimide or polyamideimide and a small amount of an aromatic or aliphatic polyamide as the flow promoter. The resulting compositions may be used in thinner-wall applications while still retaining the advantageous physical properties of reinforced polyimide compositions not having the flow promoter. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
