Abstract

Production of maleimide resin emulsion is carried out by adding maleimide monomer, aryl vinyl monomer, nitrile aryl monomer and evocating agent into mixing tank, agitating while mixing to obtain homogeneous monomer mixed liquid(a), adding emulsifier into reactor, agitating while raising temperature, adding (a) into reactor continuously, and polymerizing to form resin emulsion(b). It has excellent appearance and uniform structure, better heat-resistance and polymerization efficiency. It can be used to modify ABS, PC and PBT materials and parts of vehicles and household electrical appliances.

Description

technical field

[0001] The invention relates to a method for preparing a polymer emulsion, in particular to a method for preparing a maleimide resin emulsion. Background technique

[0002] Free radical copolymers of maleimide monomers have attracted extensive attention because of their molecular chains containing a planar five-membered ring structure, which can effectively inhibit chain rotation and thus have high structural rigidity and thermal stability. Among them, there are many studies on the copolymers of maleimide monomers and aryl vinyl monomers.

[0003] The preparation of ultra-high heat-resistant ABS resin includes alloy method and copolymerization modification method, among which copolymerization modification method is a better technical route. The alloy method mainly refers to the PC / ABS alloy. The copolymerization modification method is mainly composed of two parts of technology, one part is the maleimide monomer of maleimide (IMID) and aryl vinyl monomer (AE...
