Cross metathesis functionalization of polyolefins.
A cross metathesis strategy is reported for the post-polymerization functionalization of the pendant vinyl groups present in a range of polyolefin architectures. This represents a general strategy for the synthesis of tailored random and block copolymers as well as homopolymers.
متن کاملPolyolefins, a Success Story
This paper reports the principal discoveries which have played a major role in the polyolefin field and have positioned polyolefins as the most produced plastics. The early development of polyolefins covering the production of LDPE (Low density polyethylene) at ICI (Imperial Chemical Industries) and the discovery of Phillips or Ziegler-Natta catalysts are highlighted in the first section. In th...
متن کاملSynthesis of degradable model networks via ATRP and click chemistry.
A simple scheme involving atom transfer radical polymerization (ATRP) from a bifunctional initiator, conversion of the bromine end groups of the resulting telechelic polymer to azides, and cross-linking of this azido-telechelic macromonomer with multi-acetylene functionalized small molecules via copper-catalyzed azide-alkyne cycloaddition was employed to prepare the first tert-butyl acrylate mo...
متن کاملSynthesis of (Bio)degradable Polymers via Thiol-ene Click Polymerization
Towards the development of (bio)degradable polymers with medical relevance a non-radical thiolene synthesis route is investigated. In this work, step growth polymerization based on Michael addition click reactions is presented. Homotelechelic RAFT polymers were conjugated leading to polymers with molar weight distribution typical for a step growth polymerization, tailing up to 100 000 g∙mol-1 i...
متن کاملSynthesis of enzyme-degradable, peptide-cross-linked dextran hydrogels.
Hydrogels derived from synthetic polymers have been previously engineered to degrade under the activity of matrix metalloproteinases (MMPs). It is believed that these systems can act as extracellular-matrix (ECM) equivalents mimicking the degradation and remodeling of the ECM through the activity of cell-secreted enzymes. In this study, MMP-sensitive hydrogels derived from dextran were develope...
