The invention concerns a method for preparing an adhesive composition using an extruder having at least two rotating screws, successively comprising:

Production of an adhesive composition in an extruder

Provided herein is a copolymer of ethylene and acrylate(s) having a melt flow index (MFI) greater than or equal to 50 g/10 minutes, obtained by free-radical copolymerisation under high pressure carried out in a tubular reactor, and methods of using the same. Also provided herein is a thermoplastic composition, particularly intended to be extruded or injection moulded, having one or more copolymers of ethylene and acrylate(s) at a content ranging from 0.1 to 20 wt. %, and one or more thermoplastic polymers.

Use of a copolymer of ethylene and of acrylate(s) prepared in a tubular reactor for modifying the melt rheology of a thermoplastic composition

A rubber composition is based on at least: a copolymer A, with a content of greater than or equal to 50 phr, said copolymer A being a copolymer based on at least one ethylene monomer and on at least one vinyl acetate monomer a reinforcing inorganic filler as agent for coupling between said copolymer A and said reinforcing inorganic filler, a copolymer B different from said copolymer A, said copolymer B being a copolymer based on at least one alpha-olefin monomer and on at least one functional monomer Y; and a peroxide crosslinking system. This composition is especially intended for the manufacture of semi-finished products for tires or for the manufacture of tires.

Reinforced rubber composition

The invention provides a composition exhibiting improved impact resistance at low levels of impact modifier. The composition comprises a polyhydroxyalkanoic acid and:

Polyhydroxyalkanoate composition exhibiting improved impact resistance at low levels of impact modifier

A method for manufacturing a thermoplastic composition including: a polyester resin (c); a mixture including a copolymer (a) of an &#x3b1;-olefin and of a monomer having an ethylenic unsaturation and an epoxy function, as well as a core-shell compound (b); characterized in that said method includes a first step of manufacture the mixture of (a) and (b) by extrusion at a temperature at which the copolymer (a) is in the molten state and at a maximum temperature of 60 to 180&#xb0; C.; a second step of manufacturing the thermoplastic composition by extrusion or by mixing the polyester resin (c) with the mixture of (a) and (b) produced in the first step.
