A norbornene functionalized alkyne-Pd(II) complex was designed and synthesized, which copolymerized with a bisnorbornene cross linker via ring-opening metathesis polymerization (ROMP) afforded a cross-linked Pd(II) macroinitiator. Living polymerization of phenyl isocyanides with the Pd(II) macroinitiator lead to the formation of well-defined core cross-linked star polymer carrying helical poly(phenyl...
It is still a challenge to control the structure and functionality of a porous material in a way that its properties can be changed by external triggers. To this end, the combination of porous paper substrates with redox-responsive ferrocene-containing polymer brushes is a promising approach. Here, surface-initiated Atom Transfer Radical Polymerization (SI-ATRP) protocols for a ferrocenyl methacrylate...
An intensification and integration process of preparing highly thermal stable polylactide was reported. Calcium complex 1 [LCaN(SiMe3)2]2 (L = 2,5-bis-((pyrrolidin-1-yl)methene)-1H-pyrrole) was employed to synthesize the alcoholic chain-transfer agent and catalyze the immortal ring-opening polymerization of l-lactide in one pot. 1H NMR spectrum and MALDI-TOF mass spectrum analyses indicated that the...
In this article, we described the synthesis of comb oligomers having rigid racemic or chiral binaphthyl macrocyclic pendant groups via the free radical polymerization. Oligomers obtained were well characterized by MALDI-TOF-MS, 1 H NMR, FT-IR, UV, CD and SEC. These comb oligomers having macrocyclic pendant groups showed very good solubility in common organic solvents at room temperature. Furthermore,...
