摘要

摘要:设计并制备了具有过氧化物基团和可聚合乙烯基双键的新型过氧化物引发单体。本文以过氧化氢叔丁基和2-溴乙醇为原料，通过三步简单化学反应制备了一种过氧化物引发单体2-(叔丁基过氧)甲基丙烯酸乙酯(BPEMA)，低温反应得到2-叔丁基过氧乙醇，再与甲基丙烯酰氯或异丁基氯酯化，得到过氧化物引发单体2-(叔丁基过氧)甲基丙烯酸乙酯(BPEMA)。设计并制备了类似的过氧化物引发化合物2-(叔丁基过氧)异丁酸乙酯(BPEIB)，反应与BPEMA相同。另一种过氧化物引发单体2-过氧化氢甲基丙烯酸乙酯(HPEMA)。经测定，三种产品的纯度均在95%以上。在此，开发方便有效的方法，利用过氧化物引发单体对支化聚合物的制备进行深入研究。

Facile synthesis and characterization of peroxy-initiated monomers

ABSTRACT Novel peroxide-initiating monomer with the peroxide group and the polymerizable vinyl double bond was designed and prepared through cheap industrial chemical reactants and facile synthesis. Here, one kind of the peroxide-initiating monomer 2-(tert-butylperoxy)ethyl methacrylate (BPEMA) prepared through three-step simple chemical reactions, using tert-butyl hydroperoxide and 2-bromoethanol as the raw ingredients, which reacted at low temperature and obtained the 2-tert-butyl peroxy ethanol, then esterified with methacryloyl chloride or isobutyryl chloride to obtain the peroxide-initiating monomer 2-(tert-butylperoxy)ethyl methacrylate(BPEMA). The analogue peroxide-initiating compound 2-(tert-butylperoxy)ethyl isobutyrate (BPEIB) was designed and obtained using the same reactions as those employed with BPEMA. The other kind of the peroxide-initiating monomer 2-hydroperoxide ethyl methacrylate (HPEMA). The purity of the three products was determined to be above 95%. Here, develop convenient and effective methods in using peroxide-initiating monomer for the in-depth study on the preparation of branched polymers.

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
