The influence of catalyst on the copolymerization of epoxy and cyanate was investigated, and the mechanism of their copolymerization was discussed. the catalyst can obviously accelerate the curing of the resin to decrease the curing temperature. the three kinds of reactions ( cyclotrimerization, co - reaction and polyetherification ) in their copolymerization are not simultneous and independent to each other. in the lack of cyanate functional group, the main structures are oxazoine and polyether structure in the cured resin, and the triazine ring structure is of miner importance
研究了催化劑對環氧樹脂與氰酸酯樹脂的共聚固化反應行為的影響，並初步探索氰酸酯/環氧固化的反應歷程.研究表明，催化劑能明顯地促進其固化反應，降低固化溫度，縮短固化時間；氰酸酯與環氧共聚反應歷程是首先氰酸酯三聚反應生成三嗪環結構，然後三嗪環開環與環氧共聚反應，最後是未能參與共聚反應的環氧官能團在唑啉結構和三嗪環的催化下發生聚醚化反應；在氰酸酯官能團欠量的條件下，固化樹脂中主要是唑啉和聚醚結構，而三嗪環結構的含量很少Glycolipids ( glycosyldiacylglycerols ) are diacylglycerols with a sugar attached to the unesterified hydroxyl group
糖酯類物質是由甘油二酯和糖結合未酯化的羥基形成的。There were 29 fat soluble constituents identified of which fatty acid methyl esters made up 99. 32 % ( 12. 36 % saturated fatty acid methyl esters and 86. 96 % unsaturated fatty acid methyl esters ) and 13 constituents had not been previously reported in other studies
共鑒定29種脂溶性成分，其中脂肪酸甲酯化產物佔99 . 32 % （其中飽和脂肪酸甲酯為12 . 36 % ，不飽和脂肪酸甲酯為86 . 96 % ） ， 13種成分在火麻仁脂溶性成分的研究中未見報道。Graft copolymerization of methyl methacrylate onto carboxymethyl chitin was carried out by stirring quickly and no emulsifier, without emulsifier made the products more pure
摘要通過高速攪拌，未使用乳化劑，制備了羧甲基甲殼素和甲基丙烯酸甲酯的接枝共聚物，避免了產物中引入乳化劑雜質。Materials for printed boards and other interconnecting structures - part 2 - 10 : reinforced base materials clad and unclad - cyanate ester, brominated epoxide, modified or unmodified, woven e - glass reinforced laminated sheets of defined flammability vertical burning test, copper - clad
