Biocatalytic synthesis of δ-gluconolactone and ε-caprolactone copolymers.
The biodegradability and biocompatibility properties of ε-caprolactone homopolymers place it as a valuable raw material, particularly for controlled drug delivery and tissue engineering applications. However, the usefulness of such materials is limited by their low hydrophilicity and slow biodegradation rate. In order to improve polycaprolactone properties and functionalities, copolymerization ...
متن کاملAcrylonitrile Block and Graft Copolymers
This paper presents a review of the methods available for preparing block and graft copolymers in which one component is acrylonitrile. Methods using polymer ions and polymer radicals are considered together with a useful new technique based on reactions of nitrile groups with amide compounds of group IV transition metals. Because of its polarity and its unusual solubility properties, a polyacr...
متن کاملSynthesis and evaluation of triazole-linked poly(ε-caprolactone)-graft-poly(2-methyl-2-oxazoline) copolymers as potential drug carriers.
Well-defined graft copolymers were obtained using a copper-catalysed azide-alkyne Huisgen's cycloaddition click reaction from both biocompatible and non-toxic poly(ε-caprolactone) and poly(2-methyl-2-oxazoline) homopolymers. Resulting amphiphilic copolymers proved to form micelles that could be used as potential drug carriers.
متن کاملRapid Analysis of Starch Graft Copolymers
Starch graft copolymers are expected to become increasingly important as industrial and consumer chemicals in a large variety of end uses. Therefore, a quick and accurate analytical characterization of the graft copolymer is desirable. Vinyl side chains from starch-vinyl graft copolymers have preViously been isolated by several methods. Brockway (1) hydrolyzed the starch moiety with 1 N HCl at ...
متن کاملSynthesis and Characterization of Biodegradable Semi-Interpenetrating Polymer Networks Based on Star-Shaped Copolymers of ɛ-Caprolactone and Lactide
In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...
