文摘

We report new application fields of telechelic polymers synthesized via chain-end functionalizations of living polymers readily prepared from anionic polymerizations using lithium naphthalenide. The molecular weights of functionalized polymers were controlled in the range of 2000–50,000 g/mol. The functionalization yields were over 98mol % on the basis of the results by ¹H NMR analysis. Among several telechelic polymers, dilithium α,ω-disulfonated polystyrene could be used as an efficient compatibilizer to control the morphologies of the polystyrene/nylon 6 or the polystyrene/poly(ethylene terephthalate) blend systems through the ionic-dipole interaction mechanism. All telechelic polymers carrying hydoxylate, carboxylate, sulfonate, and thiol groups were successfully used as the polymer stabilizers for preparation of nano-sized cadmium sulfide (CdS) semiconductor in the range of 5–30 nm.
