| titleOfInvention | Maleic acid and acrylate copolymer, preparation method and application thereof |
| abstract | The invention relates to a maleic acid and acrylate copolymer, a preparation method and application thereof. The invention provides a copolymer of maleic acid and acrylic ester, which is composed of maleic acid units and acrylic ester units, wherein the number average molecular weight of the copolymer is 2000-16000, and the weight average molecular weight is 2700-20000. The invention also provides a preparation method of the copolymer, which comprises the following steps: (1) mixing maleic anhydride and a catalyst to obtain a mixture, and heating; (2) and (3) simultaneously dropwise adding acrylic ester and an initiator into the mixture for reaction to obtain the copolymer of maleic acid and acrylic ester. The copolymer contains carboxyl, hydroxyl and ester groups, has good scale inhibition performance and biodegradation performance, has good compatibility with a biocide, small addition amount, low use cost, convenient operation and no pollution in discharge, and only needs to be added into a system according to required concentration when in use, thereby having good application prospect. |
