Abstract: In this study, PMMA and PGMA were successfully synthesized by ATRP in ionic liquid, ethylenediamine / CuBr as catalyst system and ethyl dibromoisobutyrate as initiator under certain reaction conditions. The conversion rate was 70%. By changing some reaction conditions, such as reaction temperature, reaction time, initiator dosage, ligand type and dosage, the polymer molecular weight and molecular weight distribution can be precisely controlled. Through the characterization of ATR-FTIR and 1H-NMR, PMMA and PGMA were successfully synthesized. Gel permeation chromatography (GPC) was used to test the molecular weight and molecular weight distribution of polymers. The results showed that the reaction was a first-stage polymerization reaction, and the activity of the polymerization process was controllable; the molecular weight of the polymer chain increased linearly with the increase of conversion. The average molecular weight of the polymer was kept within a certain value, and the molecular weight distribution was narrow.
Key words: atom transfer radical polymerization; entanglement molecular weight controllable; molecular weight distribution; polymerization kinetics (R-03)
赫斯基致力于可持续包装解决方案
Husky is committed to sustainable packaging solutions
随着回收PET 的高需求和可回收性成为许多品牌所有者的主要可持续目标，赫斯基注塑系统致力于为下一代提供可持续包装解决方案。

该公司表示，赫斯基一直以来都是具有社会责任感和环境意识的全球参与者，并致力于将可持续发展目标与塑料包装的许多积极属性结合起来，产生积极影响。

对于寻找碳足迹更低、包含更多可回收内容包装的客户，赫斯基提供了一系列解决方案，以便在包装中使用更多消费后树脂(PCR )，包括能够处理100%回收内容的PET 预成型成型系统和用于其多层技术的PCR 选项。

“我们新的PTE 预成型技术提供了广泛的解决方案，帮助我们的客户在他们的制造运营中实现最大的灵活性、用户友好性、能效和生产力，”赫斯基硬包装总裁Robert Domodossola 在一份新闻稿中说。

赫斯基还在开发更节能的系统，并增加了轻量化能力和创新的系留封口设计，以满足回收和包装法规的要求。

赫斯基目前正在开发一种新的系统，专注于整合聚合酶链反应，使客户能够在未来24个月内每年将超过6 000万kg 的PET 带入循环经济。

该公司指出，该系统与净化回收材料的设备一起工作，消除了造粒和重熔的中间步骤，降低了成本，同时确保了包装质量。

赫斯基负责创新和可持续发展的副总裁Joachim Niewels 说：“使包装中含有更多可回收的内容、研究创新和可持续的材料、找到更有效的生产方法、减少注射成型过程中的浪费，这些都是影响我们的客户寻找更可持续发展的方法的因素。

对于赫斯基来说，创新是我们的DNA 。

我们通过不断寻找新的解决方案，进一步提高可持续性和价值，努力成为我们的客户、行业和环境的合作伙伴。
