hydroxyl group

The presence of a hydroxyl group on the molecular chain will improve the molecule's hydrophilicity [13,14], and thus its solubility, and can also inhibit the formation of macroporous structures in the membrane cross section [15].

* Improvements in moisture regain (more hydroxyl group).

Figure 4(a) shows IR absorption bands of stretching vibration of the hydroxyl group (OH), 3600-3100 [cm.sup.-1] of LDPE films exposed to C[O.sub.2] laser radiation at different fluencies and PE-BIO without exposure to C[O.sub.2] laser radiation.

Namely, compounds which possess the hydroxyl group in position C2 have IHB between hydrogen atom of the hydroxyl group and carbonyl oxygen of the carboxyl group.

9,168,218 B2; L'Oreal has patented a composition that contains photoluminescent polymer (PLP), which is a polyester synthesized from a multifunctional monomer containing two carboxylic acid groups and a functional moiety comprising a carboxylic acid group or a hydroxyl group, and a diol.

The hydroxyl groups on C2 and C3 of the glucose units are located at the top of the torus and the hydroxyl group on C6 is located at the base of the torus.

The team, which includes chemistry professor Stephen Hanessian, initially examined the possibility of simply removing a hydroxyl group from neomycin to limit the effectiveness of the aminoglycoside-inactivating enzyme.

The researchers synthesized gold nanoparticles whose surfaces were modified with various functional groups: a positively-charged amino group (-NH2), a negatively-charged carboxyl group (-COOH) or a neutral hydroxyl group (-OH).

(1,8-10) In the case of this system, the formed film with high crosslinking density can be obtained due to the reaction between PIH and the active hydrogen (hydroxyl group, amine group, or carboxyl acid) in the polymers.
