The EPR4434 resin consists of 25%-50% 1,6-hexanediol
diglycidyl ether, 25%-50% methylenedianiline, and 25%-50%, bisphenol F diglycidyl ether (DGEBF).
diacrylate (HDDA) with a viscosity of 10 cP at 25[degrees]C
One of the polyols was polytetramethylene glycol (PTMEG) with molecular weight 1000 Da and it was chosen to obtain polyether diol-based polyurethanes (the typical formulation in the current internal coating for pipeline), and the other polyol was a copolymer of polycarbonate of 1,6-hexanediol
and 1,5-pentanediol of molecular weight 500 Da--PCD--(Eternacoll[R] PH50, UBE Chemical Europe S.
Market - Trends and Forecasts to 2019
BASF increases its prices for 1,6-hexanediol
(HDO) in Europe with immediate effect or as contracts allow by 150 Euro per ton.
p-Tolualdehyde, sebacoyl chloride, 1,6-hexanediol
, DMAP, triethylamine, DMF, and piperidine (Aldrich) were used as received.
diacrylate (HDDA) and 2-ethyl-2-hydroxymelhyl-l,3-propanc-diol triacrylale (TMPTA) used as reactive diluents were obtained from Eastern Acrylic Chemical Technology Co.
Effect of temperature on the volumetric properties of dilute aqueous solutions of 1,2-hexanediol, 1,5-hexanediol, 1,6-hexanediol
, and 2,5-hexanediol, J.
In addition, Ube Industries manufactures the principal ingredients 1,6-hexanediol
and dimethyl carboxylate (DMC) used in PCD, to offer a cost competitive advantage over other manufacturers.
For this study, we chose in situ polymerization using the monomer 1,6-hexanediol
dimethacrylate to enhance bending strength and stiffness.

1,5-pentanediol (n = 3) is used in the synthesis of some specialty polyurethanes and 1,6-hexanediol
(n = 4) could find use in new polymer formulations or also serve as a potential precursor for Nylon-6,6[TM] production.
