Anionic amphiphilic end‐linked conetworks by the combination of quasiliving carbocationic and group transfer polymerizations

Abstract: A series of amphiphilic end-linked conetworks was synthesized by the combination of two ''quasiliving'' polymerization techniques, quasiliving carbocationic (QLCCP) and group transfer polymerizations (GTP). The hydrophobic monomer was polyisobutylene methacrylate synthesized by the QLCCP of isobutylene and subsequent terminal modification reactions. The hydrophilic monomer was methacrylic acid (MAA) introduced via the polymerization of 2-tetrahydropyranyl methacrylate followed by acid hydrolysis after (co)netw… Show more

“…The M n s of the polymers and their precursors were higher than the theoretical M w s due to partial deactivation of the initiator. This is in agreement with other studies where the polymers were synthesized by GTP and a high M w monomer, like PEGMA, was used which could not be distilled 38–41…”

“…The protective group of tetrahydropyranyl was chosen because is a good leaving group and it can be easily be hydrolysed even in macrogels. [28][29][30][31] The hydrolysis of the THPA groups produced anionic gels and we have chosen anionic gels because they have shown promised in drug delivery 32 and protein delivery 33 . Specifically in this study microgels of differing crosslinking ratios were produced, collected and polymerised off the chip and then hydrolysed to produce AA based microgels.…”

“…Amphiphilic conetwork (APCN), a novel polymeric material consisting of hydrophilic and hydrophobic polymer segments through covalently interconnection, has become one of the forefronts in biomaterial research . The extraordinary composition of the networks exhibit unique properties, that is, swelling dependence on solvent, phase separation at nanoscale, mechanical stability, and excellent biocompatibility, which renders them suitable for versatile applications in controlled drug delivery, extended‐wear contact lenses, and biochemical sensors …”
