Abstract

The invention discloses an EEA grafted copolymer, which is prepared from the following components in parts by weight: 90 to 110 parts of EEA, 1 to 8 parts of methacrylic acid and 0.1 to 0.5 part of initiator. The invention also discloses a reactive extrusion production method of the EEA grafted copolymer, which comprises the following steps: adding the EEA into a first hopper of a double-screw extruder, adding the methacrylic acid and the initiator into a second hopper of the double-screw extruder, and extruding and granulating in the double-screw extruder. According to the method, the EEA grafted copolymer is obtained by adding the polar monomer methacrylic acid, which is capable of reacting, into the EEA, and carrying out grafting reaction during an extruding process; a grafted product is enabled to keep higher mechanical property after being filled with a large amount of filler, and the mechanical property is observably higher than that of the EEA.
