利用功能性单体甲基丙烯酸、甲基丙烯酸十八烷基酯和聚乙二醇甲基丙烯酸酯通过常规自由基无规共聚反应,合成了两亲性共聚物Poly(MAA-SMA-PEGMA)。

A photosensitive resin for UV curing acrylic powder coating has been synthesized by esterification of methacrylic acid and GMA-type acrylic resin at the presence of ethyl acetate as solvent, tetramethylammonium chloride as catalyst, YK as inhibitor.

以醋酸丁酯为溶剂,四甲基氯化铵为催化剂,氮氧自由基为阻聚剂,由甲基丙烯酸缩水甘油酯类丙烯酸树脂与甲基丙烯酸酯化反应制得了UV固化粉末涂料用感光性丙烯酸树脂。

A series of UV curable waterborne hyperbranched polyester s with different acid/amine terminal rate,which contained -OH?-COOH and methacrylic chain end groups,and were partly neutralized with thertiary amine,were synthesized from trimellitic anhydride,epichlorohydrin,glycidyl methacrylate and triethylamine.

The macromer, methoxy polyethylene glycol methacrylate, used for polycarboxylate based superplasticizer was prepared by esterification of methacrylic acid and methoxy polyethylene glycol.

以聚乙二醇单甲醚和甲基丙烯酸为主要原料,通过酯化反应制备聚羧酸系减水剂大单体聚乙二醇单甲醚甲基丙烯酸酯。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束,由于中间亲水嵌段的作用,使PNIPAM的相转变温度提高,且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低,因此我们只能看到一个转变过程。2、通过原子转移自由基聚合,我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物,将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。
