环氧树脂因其具有良好的粘结性、化学稳定性、低收缩、优异的机械性能、易加工成型和成本低廉等优点,而广泛应用于粘结剂、涂料及电子封装等领域。但是环氧树脂存在内应力大、质脆,耐热性及阻燃性能不足而使其应用受到限制。建立新型无卤、无毒的环氧树脂阻燃体系已成为科研工作者关注的研究热点之一。本文首先通过可逆加成断裂链转移自由基聚合(RAFT聚合)合成具有反应性的两嵌段共聚物PMAiBuPOSS-b-PGMA(PMG),并将其用于环氧树脂改性研究。在PMG基础上,进一步通过开环反应将9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)接枝到PMG上,形成一种含磷(P)、硅(Si)协同阻燃的新型嵌...As we all known, epoxy resin presents attractive characteristics, including excellent adhesion, chemical resistance, low shrinkage, superior mechanical properties, low cost and simplicity in processing, So they are widely used in the fields of coatings, adhesives, casting, and electronic encapsulating etc. Building a new type of halogen-free, non-toxic flame retardant epoxy system has became one o...学位:理学硕士院系专业:材料学院_高分子化学与物理学号:2072011115008
