摘要:
An isolated nucleic acid fragment encoding an LPAAT isozyme is disclosed. Construction of a chimeric gene encoding all or a portion of the LPAAT isozyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the LPAAT isozyme in a transformed host cell is also disclosed.
摘要:
An optical article made of a transparent polymer which includes terephthaloyl moieties, optionally, other aromatic diacid moieties; ethylene glycol moieties; isosorbide moieties; and, optionally, one or more other diol moieties, wherein the polymer has an inherent viscosity of at least about 0.35 dL/g as measured on a 1% solution (weight/volume) in o-chlorophenol at 25.degree. C.
摘要:
When small amounts of zeolite or titanosilicates are added to thermotropic liquid crystalline aromatic polyester, poly(ester-amide) or poly(ester-imide) compositions, the compositions become less flammable. In many cases addition of the zeolite or titanosilicates does not significantly affect other properties of the composition, which may be used as molding resins, for instance to make parts useful in the electrical, electronic or automotive industry.
摘要:
This continuous process for preparing an aqueous mixture of .di-elect cons.-caprolactam and 6-aminocaproic acid and/or 6-aminocaproamide by involves, as the reductive amination step, continuously contacting 5-formylvaleric acid or an alkyl 5-formylvalerate in water as solvent with hydrogen and an excess of ammonia in the presence of a ruthenium on carrier, as a catalyst, wherein the carrier is at least one of titanium oxide or zirconium oxide. The aqueous mixture can be used to prepare .di-elect cons.-caprolactam.
