1 to 3 wt% isophorone
diisocyanate is added as the coupling agent along with 5 to 40 wt% 1,6-hexamethylene diisocyanate as the impact modifier.
The film-forming polymer comprises polyoxypropylene (17) isophorone
diisocyanate and dimethylol propionic acid copolymer (PPG-17/IPDI/DMPA copolymer).
Evonik Industries AG has combined its isophorone
chemistry and epoxy curing agents business in a new Crosslinkers Business Line.

Some of these compounds, which include carbonyl compounds, cyclohexanone, phenol and isophorone
, might be critical when present in higher concentrations in children's toys.
diisocyanate (IPDI), 2,2-bis(hydroxymethyl) dimethylolpropionic acid (DMPA), dibutyltin dilaurate (BDLT) and tetrahydrofuran (THF) were purchased from Aldrich (St.
This hydroxylated CSO (HCSO) was polymerized with isophorone
diisocyanate at different NCO-to-OH ratios to furnish polyurethane coatings of different composition.
Conveniently synthesized isophorone
dyes for high efficiency dye-sensitized solar cells: tuning photovoltaic performance by structural modification of donor group in donor-[pi]-acceptor system.
The topics include nano-sized and nano-crystalline sulfated zirconia solid acid catalysts for organic synthesis, incorporating modified nano-montmorillonite in polyurethane coating base on acrylic copolymer and trimer of isophorone
diisocyanate, thermal conductivity of nanofluids, the stability of nanofluids, solid oxide fuel cell as a future source of power and heat generation, and carbon doping to enhance the photofunctions of dye-encapsulated photocatalytic activity of nano-titanium oxide.
Perstorp), 2-hydroxyethyl methaerylate (HEMA, Merck), ethylene carbonate (Fluka), sodium carbonate (Merck), isophorone
diisocyanate (IPD1, Bayer), adipic acid (Merck), titanium tetraisopropoxide (TTIP, Fluka), and dibutyltin dilaurate (DBTL, Sigma-Aldrich) were used without further purification.
In this paper, we describe the first total synthesis of 1 starting from readily available isophorone
4, as outlined in Scheme 1.
