As a matter of fact, TPPI's project --which requires an investment commitment of US$ 2,300 million-- is an integrated olefinic
and aromatic center.
03 (Table 1) indicating 1 as a steroid with two hydroxyls and an olefinic
moieties in the steroidal nucleus .
Ryntz noted that demand for olefinic
materials continues to increase for auto interior applications, owing to their low specific gravity and balance of toughness, strength, aesthetics, and processability.
Compared to 2, one olefinic
proton having a large coupling constant (~16.
The petrochemical units, on the other hand, will enhance the value of the olefinic
streams coming from the RAPID steam cracker by producing various merchant grades petrochemicals products such as polyethylene, polypropylene, synthetic rubbers and other petrochemicals products.
The EIMS spectrum showed the intense peak at m/z 139 and 156 due to the loss of side chain as well as D ring fission, revealing the two oxygen atoms and an olefinic
functionality in the steroidal nucleus and one C=C bond in the side chain .
The partners intend to develop further technologies for the production of other olefinic
monomers by processing bio-derived higher alcohols.
One extrusion processor was emphatic to me about it: "If you extrude olefinic
or thermoplastic elastomeric compounds," he told me, "you will experience the die drool problem.
The company recommends the new additive for use in HDPE resin, and suggests evaluation in other olefinic
materials, as well.
The new technology is described as combining the company's Insite technology with new catalysts to produce a versatile family of olefinic
The Resins North America group of Himont, Wilmington, DE, has introduced a new family of olefinic
copolymers using the company's proprietary Catalloy process technology.
Polyolefin Resins are polymers that possess one or more olefinic
groups and are derived from hydrocarbon molecules.
