Patent number: 11578154Abstract: A method for manufacturing a polymer emulsion includes the following steps. A mixture is heated to a first temperature less than or equal to about 40° C. The mixture including about 100 to about 500 parts by weight of a monomer and about 0.5 to about 95 parts by weight of a first cross-linking agent, in which the monomer has a structure of formula (I): and R1, R2, and R3 represent H or C1-C4 alkyl group, respectively. About 0.005 to about 5 parts by weight of a first initiator is added. About 0.003 to about 5 parts by weight of a reducing agent is added to form an intermediate product. The intermediate product is heated to a second temperature less than or equal to about 92° C.Type: GrantFiled: March 22, 2021Date of Patent: February 14, 2023Inventor: Jen-Yu Liu
