文摘:研究了當用熱塑性樹脂作為不飽和聚酯樹脂低收縮劑時,合成了以苯乙烯為主鏈,聚酯為枝鏈的梳狀接枝共聚物,作低收縮劑的分散穩定劑,配合相應組成的不飽和聚酯樹脂得到了具有低收縮特性的不飽和聚酯組成物。 -
In this paper, a new class of concrete high performance water reducer ( hpwr ) was designed from chemical classification of high performance wra, working principle and unit structure model of poly - carboxylate series wra. the comb - like copolymer structure of hpwr was " carboxylic group - ether link - ester link ". the synthetic chemical materials was polyethylene glycil, acrylic acid and methyl - metacrylic acid ester
本文從高性能減水劑的化學結構、作用機理以及聚羧酸類減水劑的單元結構模型出發,設計出國內所沒有的一類新型高性能減水劑? ? 「羧酸?醚鍵?酯鍵」為單元結構模型的梳型分子結構的減水劑共聚物,並確定了以聚乙二醇( peg )系列、丙烯酸( aa ) 、甲基丙烯酸甲酯( mma )為合成該類減水劑的主要化學原料。
