摘要:
A thixotropic agent comprised of a gel which is comprised of a polymeric organic material cross-linked with certain boehmite aluminas having a crystallite size of less than about 100 Å as measured on the 120 plane.
摘要:
The present invention relates to a catalyst composition comprising titanium-, zirconium- and/or hafnium amidinate complexes and/or titanium-, zirconium- and/or hafnium guanidinate complexes and organo aluminium and/or organo zinc compounds, a coordinative chain transfer polymerization process employing the catalyst composition as well as long chain alcohols obtained by such process.
摘要:
Magnesium aluminate spinels are made by hydrothermally aging an aqueous slurry of a spinel precursor which can be (a) a mixture of boehmite alumina and a magnesium precursor, (b) an aluminum magnesium oxide or hydroxide, and (c) mixtures thereof. At least one of the aged slurries is dried to remove water and produce at least one dried spinel precursor. The dried spinel precursor is then calcined to produce the magnesium aluminate spinel.
