A new method to prepare nanostructured hybrid hydrogels by incorporating well-defined poly(oligo (ethylene oxide) monomethyl ether methacrylate) (POEO(300)MA) nanogels of sizes 110-120 nm into a larger three-dimensional (3D) matrix was developed for drug delivery scaffolds for tissue engineering applications. Rhodamine B isothiocyanate-labeled dextran (RITC-Dx) or fluorescein isothiocyanate-lab...

A series of ABA triblock copolymers, consisting of double-bond-containing poly(phenoxyallene) (PPOA), poly(methyl methacrylate) (PMMA), or poly(butyl acrylate) (PBA) segments, were synthesized by sequential free radical polymerization and atom transfer radical polymerization (ATRP). A new bifunctional initiator bearing azo and halogen-containing ATRP initiating groups was first prepared followe...

The synthesis of a linear polyisobutylene is achieved for the first time by free radical polymerization. reaction was performed in environmentally friendly conditions, i.e., an aqueous medium using cyclodextrin solubilizer, around room temperature. This mild and straightforward polymerization resulted predominantly polymer with low dispersity. Isobutylene also copolymerized acrylamide via this ...

Block copolymers can be obtained by combining catalytic chain transfer polymerization (CCTP) and conventional free radical emulsion of ethylene.

Thioketones are demonstrated to be suitable agents for controlling free radical polymerization processes: the polymerizations carry (pseudo) living characteristics indicating that the control process is induced by a persistent radical effect.
