Prepolymers of poly(ethylene oxide) (Pre-PEO) were synthesized by reacting azoisobutyronitrile (AIBN) with poly(ethylene glycol) (PEG), and their structures were characterized by IR and UV. The molecular weight of pre-PEO was related to the feed ratio and reaction time. These prepolymers can be used to prepare block copolymers—poly(ethylene oxide) -block-poly(butyl acrylate) (PEO-b-PBA) by r...

The purpose of this research was to synthesize and characterize a novel class of four-arm, star-shape biodegradable polymers having double-bond functionality as a precursor for free-radical polymerization, with unsaturated monomers or macromers or photocrosslinking for network formation. The synthesis involved two basic steps. First, hydroxyl-functionalized four-arm poly(_-caprolactone) s (PPCL-OH...

Poly(ethylene glycol)-block-poly(butyl acrylate) synthesized by radical polymerization in a one-step procedure were characterized by gel permeation chromatography, infrared, 1H-NMR spectroscopy, and differential scanning calorimetry (DSC). The crystalline property, emulsifying property, and phase transfer catalytic effect in the Williamson reaction were studied. It was found that the crystallinity...

polycaprolactone/poly(ethylene oxide) polylactide tricomponent copolymer (PCEL) with different compositions were synthesized by copolymerization of caprolactone and L-lactide in the presence of poly(ethylene glycol) using stannous octoate as a catalyst. The copolymers were purified and characterized by various analytical techniques such as GPC, FT-IR. 1H NMR, 13C NMR, DSC and X-ray diffractometry....
