Tetra-arm polyethylene glycol mercaptans are usually white or yellowish solid or liquid viscous depending on the molecular weight. The sulfhydryl group (SH) in its structure is a highly reactive functional group that can react with a wide range of chemicals, such as thiol-thiol coupling reactions and thiol-maleimide addition reactions. |
