Samples 2 and 4-6 reduced the molecular weight of polyether diol to achieve increasing crosslink density.
A niger transformed ([+ or -]) cis nerodilol (51) into (Z)-3,7-11-trimethyl-1,6 dodecadien-3,10,11-triol (52) and (6Z, 10E)-3,7,11-trimethyl-1,6,10-dodecatrien-3,12 diol (53) (Scheme 18).
Studies on thermoplastic polyurethanes based on new diphenylethane-derivative diols II.
This shows that order with respect to diols falls from 1 to zero at higher concentration of diols.
The purpose of this work is to explore the effect of novel poly(caprolactone) diols with pendant polymer chains on the bulk and surface properties of polyurethane (PU) coatings.
A mixture of LTX-diol and isoleukotoxin diol (iso-LTX-diol) was used because the chemical synthesis protocol routinely generates nearly equimolar mixtures of both isomers (LTX-diol + iso-LTX-diol) that have indistinguishable biological activities in our experimental systems in vitro (Markaverich et al.
n] is observed also for PU with segments of linear structure, whose soft segments are formed by PCL diols with [M.
2], (P-P = bulky chelating diphosphine ligand) of this type being employed in polyol transformations have been reported in the academic  as well as the patent literature [4,5] in the past few years, but to date their successes have been limited to the hydrogenation of terminal diol model systems, while their effectiveness with glycerol and higher polyols has so far been marginal.
This shows that it is possible to tweak the hydrophobicity of these polyol acrylates by carefully choosing the stoichiometry of a mixture of diols.
Control by sugars and diols of the immunological effect of beta glucuronidase in mice and patients with hay fever.
This is because the diols measured herein were acetylated, which makes the b value more negative by approximately two units, whereas the synthetic testosterone (6, 7) was underivatized.
This is also the first time the panel viewed this report on alkane diols' 10 cosmetic ingredients that are simple, small diols, many of which are used as solvents in cosmetics.
