Diethylene glycol phthalic anhydride polymer(CAS: 32472-85-8)

Diethylene glycol phthalic anhydride polymer has a crystalline form with a molecular weight around 300-400 g/mol. It is moderately soluble in common organic solvents like acetone and dimethylformamide. The polymer is known for its high reactivity, particularly in esterification reactions, and its thermal stability up to 250°C.

Diethylene glycol phthalic anhydride polymer is synthesized by the condensation of diethylene glycol with phthalic anhydride, typically using a catalyst such as p-toluenesulfonic acid. The process involves heating the reactants under reflux conditions to achieve high molecular weight polymers with good yields and selectivity.

Diethylene glycol phthalic anhydride polymer is widely used in the polymer industry for the production of high-performance plastics and resins. It is also utilized in the pharmaceutical industry for drug delivery systems and in the manufacturing of sensors and semiconductors due to its excellent thermal and mechanical properties.

When handling Diethylene glycol phthalic anhydride polymer, it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Operations should be conducted in a well-ventilated area or fume hood to avoid inhaling the dust or vapors. Spills should be cleaned up using appropriate absorbents, and the SDS (Safety Data Sheet) should be consulted for detailed handling and disposal instructions.
