| titleOfInvention | A kind of preparation method of emulsifier based on polyhydroxy linear polymer |
| abstract | The invention discloses a preparation method of an emulsifier based on a polyhydroxy linear polymer, and belongs to the field of polymer materials. With N,N-dimethylformamide (DMF) as solvent, N,N-dicyclohexyl carbonimide (DCC) as dehydrating agent, 4-lutidine (DMAP) as catalyst, one of the raw materials It is a polyhydroxy linear polymer (PG), another raw material is a carboxylic acid with different chain lengths, and an amphiphilic polymer emulsifier is finally obtained through the esterification reaction. The invention can change the number of hydroxyl groups of the synthetic polymer by changing the amount of the reaction monomer, adjust the HLB value of the emulsifier, which is simple and convenient, and endows the emulsifier with excellent performance; the polymer emulsifier obtained in the invention has a longer alkyl The base chain has a good encapsulation effect on mineral oil, vegetable oil and benzene oil, and has a good emulsifying effect; the process of the invention is simple in synthesis and environmentally friendly. |
