采用sol-gel法制备了纳米TiO2溶胶，并在制备过程中加人丙烯酸对生成的纳米TiO2胶体颗粒进行表面修饰，该有机包裹膜可有效抑制颗粒在反应、老化及热处理过程中发生团聚。

As raw materials was prepared by a single-step method in water solution of acetone and methyl alcohol.

对CdS/聚丙烯酸酯复合材料，应用X-射线粉末衍射、透射电镜、紫外。

AA-AM supper absorbent resin was synthesized from acrylic acid and acrylic amide by inverse suspension method.

对反相悬浮法制备丙烯酸和丙烯酰胺二元共聚高吸水性树脂的工艺进行了研究。

Terpolymer of acrylic acid/acrylic amide/malefic anhydride was synthesized and mixed with polyepoxysuccinic acid in order to improve the scale and corrosion performance of the latter in this study.

为了提高PESA的阻垢缓蚀性能，合成了丙烯酸／丙烯酰胺／马来酸酐三元共聚物，与聚环氧琥珀酸进行物理复配，考察了温度、反应物配比及浓度对复配产品阻垢和缓蚀性能的影响。

Cellulose in pulp is used as a raw material on which acrylic acid and acrylic amide are grafted when superabsorbent is polymerized.

采用纸浆纤维素为分子骨架，接枝丙烯酸及丙烯酰胺制备高吸水树脂。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.

将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。
