The thermal reaction of a bis(biphenylene) monomer, N,N ′-bis(biphenylene-2-yl)-4,4′-hexafluoroisopropylidenediphthalimide ( 3 ), with either of two diacetylenic monomers, bis(4-ethynylphenyl) ether ( 4 ) or bis[4-(phenylethynyl)phenyl] ether ( 5 ), gave polymers that contain ...
Question: A synthesis reaction involves: A. the creation of smaller molecules B. the formation of bonds C. the breaking of bonds D. the release of energy Chemical Reactions: Chemical reactions involve two or more elements that react w...
Deciphering the origins of life on a molecular level includes unravelling the numerous interactions that could occur between the most important biomolecules being the lipids, peptides and nucleotides. They were likely all present on the early Earth and a
HMAB transformation into HMPB is a fast reaction over all catalysts tested. The low hydrogenation constant of HMPB for a nonannealed catalyst clearly indicates the low activity of the catalyst. Almost negligible conversion of the first intermediate slows down or disables the downstream reactions. Ot...

It breaks down into less toxic components after biological action. Scale inhibitor HY‐818Scale inhibitor is carboxylic acid strong electrolyte scale inhibitor. Because the molecular structure contains carboxylic acid group with good scale inhibition and dispersion performance ...
What are the names of reactions that build monomers into polymers and break down polymers into monomers? What is the covalent bond between the carboxyl group on one amino acid and the amino group on the next, formed by a dehydration reaction?
