Site—site interactions in a polymer matrix: effect of amine structure on transformations of copoly(styrene—p-nitrophenylacrylate)

The role of multifunctionalized amine structure and reaction conditions on the transformations of crosslinked copoly(styrene-p-nitrophenylacrylate)

“…Introduction of a phenyl ring and a carboxylic functional group into a polymer backbone ofpared by literature methods. [14][15][16] Polymerization in the presence of chlorobenzene generated solfers the possibility to prepare new backbones with a broader variability of swelling in polar and nonvent expanded gel-type resins. Ionically, bonded bromide, chloride, and iodide was determined as polar solvents.…”

Amine Functionalisations of Glycidyl methacrylate Based PolyHIPE Monoliths

“…It has been found previously that when diamino alkanes and multi functional amines were used to transform polyacrylates and polyvinylbenzyl chloride, a substantial amount of additional cross-linking took place. [16,17,18,19] This kind of side reaction is undesired when free amino groups are needed for further functionalisations or end applications. Site-site interactions can be strongly dependent on the temperature and also on the solvent polarity.…”

Aryl acrylate porous functional polymer supports from water‐in‐oil‐in‐water multiple emulsions

“…The reason for including a commercially unavailable NPA in the polymers obtained from multiple emulsions was to obtain a polymer chain with a moiety that can be easily transformed with nucleophiles. NPA has already been used in our laboratories previously and has proven to be fairly easily to functionalise with amines, hydrazines, amino acids, amino thiols and amino alcohols 10, 11, 13. Organic synthesis has recently benefited from various insoluble polymers to which species for the removal of excessive reagents, substrates or catalysts from solutions were immobilised (the term ‘polymer‐assisted solution‐phase chemistry’ is usually used for the technique and the term ‘polymer‐supported scavengers’ for the polymers; for a review of polymer‐supported scavengers see Ley et al 19).…”

“…Alternative chemistry to chloromethylated styrene in the form of activated esters with good leaving groups was introduced into polymer supported chemistry some years ago 10. For instance, various functionalisations with amines were performed in order to acquire polymeric scavengers 11.…”

“…For instance, various functionalisations with amines were performed in order to acquire polymeric scavengers 11. Furthermore, 4‐nitrophenyl acrylate‐based beads were hydrolysed and transformed into an acid chloride serving as a precursor for further functionalisations 12, 13. Two reactive acrylates, namely 4‐nitrophenyl acrylate or 2,4,6‐trichlorophenyl acrylate, were also introduced as reactive monomers into HIPEs from which monolithic polymer supports were prepared,14 while inverse HIPEs were used to prepare acrylic acid PolyHIPEs 15.…”
