General description

Dimethyl 5-sulfoisophthalate sodium salt was used to produce a series of water-soluble polymeric surfactants.

Application

  • Enhancing poly(lactic acid) crystallization: Dimethyl 5-sulfoisophthalate sodium salt was used as a nucleating agent in poly(lactic acid), significantly improving its crystallization behavior, which is crucial for developing biodegradable plastics with enhanced mechanical properties (Jongpanya-Ngam et al., 2022).
  • Development of biodegradable polyester ionomers: A study on biodegradable aliphatic polyester ionomers, potentially incorporating Dimethyl 5-sulfoisophthalate sodium salt, focused on synthesizing environmentally friendly materials that offer practical benefits in medical and packaging applications (Han et al., 2004).
