Low-temperature and oil-resistant monomer, traditionally used alkoxy ether acrylate to participate in the copolymerization to obtain ACM with a cold-resistant temperature below -30℃; later in industrial production, methoxyethyl acrylate was used as a comonomer to produce cold-resistant ACM, further reducing the use temperature . In recent years, foreign patents reported that the use of acrylate polyethylene glycol methoxy ester, dimethoxy ethyl maleate, etc. as low-temperature oil-resistant monomers is more effective. In addition, DuPont adopts solution copolymerization of ethylene and methyl acrylate to introduce ethylene into the polymer backbone, which can significantly improve the low-temperature flexibility of the product.
Vulcanization point monomer, in order to make ACM convenient for vulcanization treatment, a certain amount of vulcanization point monomer must be added to participate in the copolymerization. Generally, the content of vulcanization point monomer is less than 5%. Vulcanization point monomer can be divided into chlorine-containing according to reactive points Type, epoxy type, carboxyl type and double bond type, etc. Among them, the industrial applications mainly include chlorine-containing vinyl chloroacetate, epoxy glycidyl methacrylate, allyl glycidyl ester, double bond type 3-methyl-2-butenyl ester, carboxylic acid type There are also patent reports using allyl acetoacetate and so on.
