PH- and Thermo-Responsive Water-Soluble Smart Polyion Complex (PIC) Vesicle with Polyampholyte Shells.

ABSTRACT: A diblock copolymer (P(VBTAC/NaSS)₁₇-b-PAPTAC₅₀; P(VS)₁₇A₅₀) composed of amphoteric random copolymer, poly(vinylbenzyl trimethylammonium chloride-co-sodium p-styrensunfonate) (P(VBTAC/NaSS); P(VS)) and cationic poly(3-(acrylamidopropyl) trimethylammonium chloride) (PAPTAC; A) block, and poly(acrylic acid) (PAAc₄₉) were prepared via a reversible addition-fragmentation chain transfer radical polymerization. Scrips V, S, and A represent VBTAC, NaSS, and PAPTAC blocks, respectively. Water-soluble polyion complex (PIC) vesicles were formed by mixing P(VS)₁₇A₅₀ and PAAc₄₉ in water under basic conditions through electrostatic interactions between the cationic PAPTAC block and PAA_c49</
