Alternating-block hyperbranched polymers were synthesized using the highly versatile thiol-yne reaction. Dimethyl acrylamide-styrene and tert-butyl acrylate-styrene polymers were prepared, with subsequent hydrolysis of the tert-butyl ester to acrylic acid. The dimethyl acrylamide-styrene hyperbranched polymers self-assembled into large aggregates, as did the acrylic acid-styrene system at low pH. However, high pH triggers the formation of very well defined small particles in the latter system.
交替嵌段超支化聚合物是通过高度通用的硫醇-炔反应合成的。制备了二甲基丙烯酰胺-苯乙烯和叔丁基丙烯酰胺-苯乙烯聚合物，然后将叔丁酯水解为丙烯酸。二甲基丙烯酰胺-苯乙烯超支化聚合物自组装成大的聚集体，而在低 pH 值下，丙烯酸-苯乙烯体系也是如此。然而，在后者体系中，高 pH 值会引发非常明确的小颗粒的形成。
