While Evonik supplies an important comonomer
for polyethylene production, SABIC contributes important raw materials for the C4 compound.
While the surface tension of the studied solutions underwent a slight increase by branching, viscosity of the diluted solutions was significantly affected by increasing the comonomer
feed ratio in which high viscosity was observed in S4 with the highest GP.
"More important, previous tests weren't applicable to polyolefins with high co-monomer content, such as some rubbery materials." At Polyolefins, Cong presented "Recent Advances and Challenges in Polyolefin Comonomer
Distribution Analysis," describing Dow's test method called "high-temperature liquid chromatography" of polyolefins.
It is established that the kinetic regularities of the polymerization process are affected by the comonomer
and mineral filler ([Al.sub.2][O.sub.3], Si[O.sub.2]) (Figure 6).
2018 Science & Technology Award winners were announced at the meeting, including Charles Goodyear Medalist Eric Baer, known for his in-depth research identifying the elastomeric behavior of polyolefins as a function of the comonomer
This PE resin used a butene comonomer
and had a base resin density of 0.935 g/cc and a melt index (MI) of 2 g/10 min.
Even more impressive 'high heat' grades were achieved by incorporating alpha methyl styrene as a comonomer
Abstract An acrylic fatty acid derivative (AcFAD) was evaluated as comonomer
for promotion of oxidative cure in waterborne latexes.
CB&I's proprietary Olefins Conversion Technology (OCT) will be used to produce 196,000 annual m tonnes (MTA) of polymer grade propylene and its Comonomer
Production Technology (CPT) to produce and recover 20,000 MTA of comonomer
grade 1-butene at the complex.
(12-15) Because FTIR measurements of DC use the aromatic carbon-carbon double bond peak as internal standard, variations in comonomer
blend composition and ratio can influence the results.
The behavior of PNIPA depends on structure of polymers, especially on the kind of comonomer
and copolymer [12-18], as well as the character of end groups [19-23].
