DuPont is developing a low temperature (<100 °C), low pressure (<100 bar) water-based miniemulsion process for the production of ethylene/vinyl acetate copolymers to replace the high temperature, high pressure (150-300 °C, 1500-3000 bar) technology used currently in industry. DuPont Canada is involved in the plans to scale-up the new process, with pilot plant design and development slated to begin in 2014. They have funded the Hutchinson group to study the underlying vinyl acetate radical polymerization mechanisms and provide accurate values of kinetic rate coefficients.

杜邦正在开发一种低温(&lt；100°C)、低压(&lt；100bar)水基微乳液工艺，用于生产乙烯/醋酸乙烯共聚物，以取代目前工业上使用的高温、高压(150-300°C，1500-3000 bar)技术。杜邦加拿大公司参与了扩大新工艺的计划，试点工厂的设计和开发计划于2014年开始。他们资助Hutchinson小组研究潜在的乙酸乙烯自由基聚合机理，并提供准确的动力学速率系数。
