Method for copolymerization of alpha-methyl styrene (AMS) and maleic anhydride (MAn) |
| abstract |
The invention provides a method for preparing an alternating copolymer of alpha-methyl styrene (AMS) and maleic anhydride (MAn), belonging to the high molecular precipitation polymerization field. The method comprises the following steps: taking the mixed solution which is formed by respectively mixing organic acid alkyl ester or ketone with alkane as reaction medium, taking organic peroxide or azo compound as an initiator to initiate monomer AMS to copolymerize MAn and preparing the copolymer microsphere of the AMS and MAn; wherein, the copolymer microsphere features uniform grain diameter and monodispersity. The method has simple process and can synthesize good dispersion system featuring uniform grain diameter and even dispersion. |
