Technical Data and Manufacturing Plants Analysis
The average cell size of FPUFs reduced from 1034 to 766 pm with the increased Mw of polyether diol
1988) reported the transformation of [beta]-myrcene (1) by Diplodia gossypina to yield three diols
known as 2-methyl-6-methylene-7-octene-2,3-diol
(3) and 7 methyl-3-methylene-6-octene-1,2-diol
(4) (Scheme 1a).
This is a typical hot liquid casting of LF p-phenylene diisocyanate (PPDI) prepolymer with diol
Poly(hexamethylene carbonate) diol
(PHMCD) was produced using 1, 6-HDL and dimethyl carbonate .
Also as PEG was replaced with more and more of butane diol
, the resulting gel absorbed less and less water.
Depending on the linear diol
monomers used, the reaction was completed in 1-4 d.
Table 2--Physical Properties of Seed Oil and Comparative Polyols Polyol Hydroxyl Diol
A series of novel silicone-modified polyesters (SPE) were first prepared by substituting part of diol
with low molecular weight hydroxyl-terminated PDMS using a method for synthesis of conventional polyester.
In terms of Kowalski's discussion on the ring opening polymerization mechanism of cyclic ester (22), PBA diol
and purified Sn[(Oct).
The Dow Chemical Company introduced UNOXOL[TM] Diol
and UCAR[TM] n-Alkyl Propionates oxygenated solvents.
Keywords: Defoamers, wetting agents, surface tension, waterborne, foam control, gemini surfactant, molecular defoamer, acetylenic diol
, surface adsorption
Phenopol INCI: phenoxyethanol, methylparaben, propylparaben, ethylparaben, butylparaben, isobutylparaben, 2-bromo-2-nitropropane-1,3 diol
, propylene glycol
Starting with these three basic raw materials, the diisocyanate can react with the OH-groups of the polymer diol
and also with those of the chain extender.
Firemaster[R] 520 is a highly reactive, proprietary, bromine-containing diol
for use with blowing agents in rigid polyurethane and polyisocyanurate (PIR) foam Firemaster 550 is a brominated non-BDE FR said to be efficient for low-density foams, offering better thermal stability and anti-scorch properties than chlorinated phosphate esters.
