The interfacial reaction between the carboxyl group
of PBMA and the amide functional group of PA 6 matrix during melt processing improved the rubber particles' dispersity and the stress transfer in the blends.
It is attained by a coating composition comprising a hydrosol emulsion and colloidal silica, wherein the hydrosol emulsion is obtained by neutralizing, with an alkali, a synthetic resin emulsion prepared by dispersing, in water, particles of a synthetic resin having a carboxyl group
and an alkoxysilyl group.
More important, the swelling of hydrogels is controlled by the amount of carboxyl group
according to Flory-Huggins-Tanaka theory (40).
has been granted a patent for a powdered thermosetting composition including a binder which is comprised of a carboxyl group
containing amorphous isophthalic acid containing polyester, a carboxyl group
containing semi-crystalline polyester, at least 10 parts by weight, based on the total weight of the binder, of a glycidyl group containing acrylic copolymer.
The polyurethane is comprised of a mixture of at least two polyurethane compounds, wherein the polyurethane compounds comprise a reaction product of a polyester polyol that contains at least one carboxyl group
, a polyol, and a polyisocyanate, wherein at least a portion of the polyol comprises a polyol that contains at least one carboxyl group
, and wherein the polyurethane compounds each have a number-average molecular weight of from 1,000 to less than 20,000.
or less, substantially free from co-solvents and having at least one carboxyl group
, a water-soluble cross-linker reactive with the carboxyl groups
This can be attributed to decrease in the crystallinity due of the presence of unreacted pendant carboxyl, hydroxyl groups, and the catalytic effect of the carboxyl group
Moreover, each CP molecule may be grafted with several different PA 6 molecules, since each CP molecule is associated with more than one carboxyl group

10x molar excess 1-ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC) and N-Hydroxysuccinimide (NHS) were added to activate the carboxyl group
of ELP to facilitate the formation of a peptide bond between ELP and PA (Figure 1).
CCP Composites US LLC has been granted a patent for a thermosetting, crosslinkable resin composition suitable for preparing a gel coat, the composition is comprised of: a polyester acrylic polymer having an average of more than two polymerizable carbon-carbon double bonds in each molecule, the carbon-carbon double bonds in the polyester acrylic polymer being from a reaction product of a saturated polyacid half-ester having an average acid functionality of two or more and an unsaturated epoxide monomer in about chemically equivalent amounts to furnish one epoxy group per carboxyl group
, the saturated polyacid half-ester being the reaction product of one or more polyols having an average of at least two hydroxy
