Butylene glycol-terephthalic acid polymer(CAS: 26062-94-2)

Butylene glycol-terephthalic acid polymer is a transparent, amorphous, and crystalline material with a high molecular weight, typically above 10,000. It has good thermal stability and low water solubility, making it suitable for various industrial applications. The polymer exhibits excellent mechanical properties and is slightly soluble in organic solvents like chlorinated hydrocarbons and esters.

Butylene glycol-terephthalic acid polymer is synthesized through a polycondensation reaction between butylene glycol and terephthalic acid, catalyzed by strong acids such as sulfuric acid. The process involves the condensation of these monomers under vacuum conditions to achieve high molecular weight polymers. The reaction yield is typically high, with good control of molecular weight and composition.

Butylene glycol-terephthalic acid polymer is widely used in the production of high-performance fibers, films, and molded parts. It is also utilized in the pharmaceutical industry for drug delivery systems, in the sensor and semiconductor industries for packaging and encapsulation materials, and in the automotive industry for its excellent thermal and mechanical properties.

When handling Butylene glycol-terephthalic acid polymer, it is important to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The material should be stored in a cool, dry place away from direct sunlight and heat sources. In case of spills, immediately clean up using appropriate absorbent materials and follow the safety data sheet (SDS) guidelines for disposal. Always work in a well-ventilated area or fume hood to avoid inhaling fumes.
