DIMETHYL-5-SULFOISOPHTHALATE SODIUM SALT(SIPM,DMSIP) Synonyms: Dimethyl-5-Sulfoisophthalate Sodium Salt; 1,3 Benzene-Dicarboxylic Acid; 5 Sulfo-1,3-Dimethyl Ester Sodium Salt; DMS; SIPM; DMSIP. CAS Registry Number CAS RNo. is: 3965-55-7 Formula Chemical formula is: C10H9O7SNa Molecular Weight MW is: 296.24 g/mol. To be used for SIPM is mainly used to produce the dyed polyester chip. It is also used in water dispersible resin systems applied in coating and adhesives. It is acting as the third monomer of cation modified polyester (CDPET). It has a good affinity function with cation dyestuff because of the CDPET fiber containing sulfo group, the dyed fiber is bright and lustrous, having a complete range of color and dying deeply. The modified fiber has woolens feeling, it is easily blended with fleece that is necessary for garments manufacturing.
