WebPoly(anhydrides) are considered as an interesting alternative polymer system given the ease of modifying the degradation rate by manipulating the ratio of monomers [17, 18]. Despite the promising characteristics of these novel polymer-based systems, longer regulatory approval times should be anticipated given the current limited knowledge of these … WebTEG-POE polymer is composed of repeating units containing a diol connected to an orthoester. Once the active components have been released from the formulation, the rate of polymer hydrolysis rapidly increases via the cleavage of the orthoester bonds, liberating small, water-soluble monomeric compounds that are rapidly cleared from the body by the … WebThe invention relates to a material for use as construction material for energy-pulse-induced transfer printing, which contains (a) at least one polymerizable binder, (b) at least one volume expansion component, (c) at least one initiator for the polymerization and (d) preferably at least one energy transformation component. The invention furthermore … icbm missile warhead
