ABC Triblock Terpolymers with Orthogonally Deprotectable Blocks: Synthesis, Characterization, and Deprotection
(2015)The development and availability of new protecting groups are vital for all branches of synthetic chemistry. Equally vital is the facile and selective removal of these groups, leaving intact other protecting groups which ...

Amphiphilic model conetworks of polyisobutylene methacrylate and 2-(dimethylamino)ethyl methacrylate prepared by the combination of quasiliving carbocationic and group transfer polymerizations
(2007)A series of amphiphilic polymer conetworks (APCN) of the hydrophobic polyisobutylene methacrylate macromonomer (PIBMA) and the ionizable hydrophilic 2-(dimethylamino)ethyl methacrylate (DMAEMA) were synthesized by combining, ...

Amphiphilic single and double networks: a small-angle X-ray scattering investigation
(2016)We investigated the microphase-separated morphologies of water-swollen amphiphilic single and double polymer networks using small-angle X-ray scattering (SAXS). The networks consist of (i) a first conetwork containing ...

Anionic amphiphilic end-linked conetworks by the combination of quasiliving carbocationic and group transfer polymerizations
(2009)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 ...

Double Networks Based on Amphiphilic Cross-Linked Star Block Copolymer First Conetworks and Randomly Cross-Linked Hydrophilic Second Networks
(2016)This study presents the preparation and characterization of double networks (DN) based on a first amphiphilic polymethacrylate conetwork (APCN) and a second polyacrylamide network. The APCN first network comprised ...

Enamine-Based Hydrophilic Dynamic Covalent Polymer Networks: Effects of pH, and Copolymer Composition and Concentration on the Aqueous Swelling Degrees and the Gel Formation Times
(2015)In this work, we explore the formation in water of dynamic covalent polymer networks cross-linked via enamine groups. The polymer networks resulted from the combination of pairs of chemically complementary hydrophilic ...

Multi-functional conetworks based on cross-linked star polymers
(2010)Three series of conetworks based on cross-linked star polymers of different architectures were prepared using group transfer polymerization. The first series of conetworks were amphiphilic, based on the hydrophobic monomer ...
