WebAlterations in the oligomer chemistry lead to changes in mechanical properties and degradation behavior. Longer PEG chains lead to more flexible materials, and the rate of mass loss decreases as hydrophobicity increases. Instead of difunctional PEG chains, tri- or multi-functional alcohols were also used as cores for such macromers. WebSep 24, 2010 · The polymeric supports play a key role in combinatory chemistry. Therefore, various kinds of functional polymer resins have been exploited as supports, reagents, and catalysts in organic synthesis.
