Evonik will also be introducing its new VESTASOL brand of specialty solvents, including isophorone, trimethylcyclohexanone (TMC-one), tetrahydronaphthalene (THN), and decahydronaphthalene
The coal fuel, decahydronaphthalene
, stood up to temperatures as high as 500 [degrees] C.
was used as spin solvent in the previous study to demonstrate the feasibility of the mechanical solvent removal process.
The mechanical solvent removal method investigated in this study applies to both volatile and nonvolatile spin solvents; however, the focus of this study was on decahydronaphthalene
For gel-spun UHMWPE, common spin-solvents include decahydronaphthalene
and paraffin oil and these spin-solvents induce a well-defined gel-transition between 101 and 108[degrees]C for UHMWPE as measured by parallel-plate rheometry .
Intrinsic viscosities of the polymer samples were determined in decahydronaphthalene
at 135 [degrees] C using an Ubbe-lohde viscometer.
3 g specimens were wrapped in a stainless steel mesh and immersed in 1000 ml of boiling decahydronaphthalene
(decalin) contained in a round bottom flask fitted with a reflux condenser.
8], where [eta] is the intrinsic viscosity of the polymer measured in decahydronaphthalene
at 135[degrees] C.
The solvent was decahydronaphthalene
, which has nearly the same reflective index as polypropylene (1.
The solvent used was decahydronaphthalene
, which is inert to and has nearly the same reflex index (1.
The inner conductor was removed and the remaining material was placed in either octane at 125[degrees]C (boiling point) or decahydronaphthalene
at both 120[degrees]C and 135[degrees]C (195[degrees]C boiling point).
The die was then treated in decahydronaphthalene
(decalin) and xylene at 130 [degrees] C for 30 rain to dissolve out the PE and PS remaining in the coated layer, respectively.
