diacrylate (HDDA) with a viscosity of 10 cP at 25[degrees]C
Market by Application (Polyurethanes, Coatings, Acrylates, Adhesives, Unsaturated Polyester Resins, Plasticizers, and Others) and By Geography (NA, Europe, Asia-Pacific, & ROW) C Trends and Forecasts to 2019" is a Apr 2014 publication of 202 pages and it says global 1,6-Hexanediol
market was estimated to be is $569 million in 2013, and is projected to reach $916 million by 2019, growing at a CAGR of 8.
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.
BASF increases its prices for 1,6-hexanediol
(HDO) in Europe with immediate effect or as contracts allow by 150 Euro per ton.
com/prnh/20130307/600769 The global 1,6-Hexanediol
market is projected to account for 186 kilotons of market volume by 2019 signifying a robust growth rate of over 6.
To increase the molecular weight, some 1,6-hexanediol
needed to be added.
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.
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.
The viscosity dependence of spin modes in the frontal polymerization of Trimethylolpropane ethoxylate triacrylate, 1,6-hexanediol
diacrylate (HDDA), and Aliquat Persulfate (thermal initiator) have been studied.
