Under the catalyst, the polymerization retarder, the including water medicinal preparation existence condition, the methylacrylic acid and the polyethylene glycol single methyl ether (400) direct esterification synthesis methylacrylic acid polyethylene glycol single methyl ether (400) ester, and the influence factors of the catalyst, polymerization retarder, including water medicinal preparation has mellowly carried on the comparison.

摘要在催化劑一区二区视频、阻聚劑丝袜欧洲另类自拍视频在线、帶水劑存在的條件下黄片在线看不卡，由甲基丙烯酸與聚乙二醇單甲醚(400)直接酯化合成甲基丙烯酸聚乙二醇單甲醚(400)酯久久久久久久一级毛片，并對酸醇比亚洲最新的黄色网站、催化劑97一级毛片全部免费播放、阻聚劑、帶水劑等影響因素進行了比較人人干人人操国产。

The research indicated that under the compound use of hydroquinone and methyl quinone or independent use of phenothiazines or nitrogen oxygen free radical made the polymerization retarder, opposite-methyl-phenylsulfon made the esterification catalyst, toluol made the backflow including water condition, the acid mellowly compared to when it was 1.15, the production rate of the synthesis methylacrylic acid polyethylene glycol single methyl ether (400) ester may achieve 98.9%, was extremely similar to the overseas product functional group structure.

研究表明99久久九九国产精品，在氫醌、甲醌復合使用或者單獨使用吩噻嗪日韩A片一级无码专区网址、氮氧自由基哌啶酮作阻聚劑饥渴熟妇高潮喷水，對甲苯磺酸作酯化催化劑、甲苯作回流帶水的條件下自拍偷2、酸醇比為1.5時在线亚洲精品专区第一页，合成的甲基丙烯酸聚乙二醇單甲醚(400)酯產率可以達到98.9%，與國外產品官能團結構十分相似黄网战亚洲。

With cerous ammonium nitric-ethylene diamine tetraacetic acid as an initiator, and with the protection of the nitrogen the graft-copolymerization of methylacrylic acid and vinyl acetate on chitosan grafting was studied.

FUMARIC ACID：富馬酸

目前國內其它眾多廠家的乙烯基生產廠家一般情況下均采用甲基丙烯酸(Methylacrylic acid)及富馬酸(Fumaric acid)改性來合成乙烯基酯樹脂,但從嚴格意義上說這種乙烯基酯樹脂不屬于乙烯基酯樹脂,而是乙烯基酯樹脂與雙酚A不飽和聚酯樹脂中的一個過渡品種,
