Hydrolyzable and biocompatible aliphatic polycarbonates with ether-functionalized side chains attached via amide linkers Aliphatic polycarbonates with ether side groups linked by amide bonds exhibit high hydrolyzability and antiplatelet properties due to enhanced hydration resulting from strong interactions with ...
isable double bonds is obtained by reaction of the amino groups of a polyamide (II) with an amino-reactive compound (III) containing polymerisable double bonds or by reaction of the carboxyl groups of (II) with a carboxyl group reactive compound (IV) containing polymerisable double bonds. ...
In thermoplastics, the polymer chains are held together by secondary bonds which form physical crosslinks such as hydrogen bonds, which are reversible. The physical crosslinks dissipate when heated past a critical temperature but reform when cooled, granting thermoplastics their reprocessable nature. ...
This study is the first to report that the heterogeneity of particle dynamics in transient networks, formed through reversible bonds, exhibits characteristics similar to those observed during sol–gel transitions.

An solid polymer electrolyte is defined as a solvent free material where the ionically conducting pathway is generated by dissolving the low lattice energy metal salts in a high molecular weight polar polymer matrix with aprotic solvent as polymers are generally electrical insulators. ...
Proteins self-assemble into certain structures in which the amino-acid side chains are positioned with atomic-level accuracy and held in place by numerous intramolecular interactions. Furthermore some proteins, such as actin1, collagen2 and amyloid3, form fibrils held together by intermolecular interac...
However, proteins that are not associated as part of a functional complex and held together will not form a methyl bridge polymer, as demonstrated by the lack of polymerisation of insulin, if that molecule function as an independant monomer. It should be noted that this does not mean ...
The folded chains are held together by localized chemical bonds. The crystalline regions are connected by amorphous regions. This definition of crystalline is different than that used for metals and ceramics. Examples of crystalline polymers include high-density polyethylene (HDPE), polypropylene (PP),...
There is clinical and scientific interest in developing local anesthetics with prolonged durations of effect from single injections. The need for such is highlighted by the current opioid epidemic. Site 1 sodium channel blockers such as tetrodotoxin (TTX
Bonded non-woven fabrics, such as the textile articles of this invention, can be defined generally as assemblies of fibers held together in a random or oriented web or mat by a bonding agent. While many non-woven materials are manufactured from crimped fibers having lengths of about 0.5 to ...
