	<span style=\"line-height:1.5;\">采用无皂种子乳液聚合方法制备了一种新型丙烯酸酯共聚物增稠剂。为了获得表面清洁和表面富含羧基的功能性聚合物乳胶粒子，首先合成了种子颗粒直径在</span><span style=\"line-height:1.5;\">250~300</span><span style=\"line-height:1.5;\">纳米的聚</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">苯乙烯</span><span style=\"line-height:1.5;\">-</span><span style=\"line-height:1.5;\">甲基丙烯酸</span><span style=\"line-height:1.5;\">)(</span><span style=\"line-height:1.5;\">P</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">St-MAA</span><span style=\"line-height:1.5;\">))</span><span style=\"line-height:1.5;\">种子乳液；然后，在无乳化剂的条件下，聚合丙烯酸乙酯</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">EA</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">，甲基丙烯酸十二酯</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">LMA</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">，苯乙烯</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">St</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">和甲基丙烯酸</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">MAA</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">；最后，得到颗粒直径在</span><span style=\"line-height:1.5;\">380~440</span><span style=\"line-height:1.5;\">纳米的稳定乳液。重点研究了甲基丙烯酸十二酯含量对乳液颗粒</span><span style=\"line-height:1.5;\">大小和乳液稳定性的影响。研究表明，该聚合物乳液具有很好的增稠性能，良好的悬浮能力，透明性好，易于</span><span style=\"line-height:1.5;\">使用。采用傅里叶变换红外光谱仪</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">FT-IR</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">、示差扫描量热仪</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">DSC</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">、透射电子显微镜</span><span style=\"line-height:1.5;\">(</span><span style=\"line-height:1.5;\">TEM</span><span style=\"line-height:1.5;\">)</span><span style=\"line-height:1.5;\">对其结构和形貌进行了表征。&lt;br/&gt;</span><span style=\"line-height:1.5;\">A kind of acrylates copolymer thickener was prepared by soap-free and seeded emulsion polymerization. In order to obtain functional polymer latex particles with clean surface and with surface carboxyl groups, Poly (styrene-methacrylic acid) (P (St-MAA)) seed particles with the diameter of 250 - 300 nm were synthesized via soap-free emulsion polymerization. Then the seeded emulsion
