  • Use of a copolymer of ethylene and of acrylate(s) prepared in a tubular reactor for modifying the melt rheology of a thermoplastic composition
    Patent number: 11555116
    Abstract: 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.
    Type: Grant
