C08L 23/04
C08L 23/10

US Classification:

525191, 525240

Abstract:

Provided is a heat-seal resin. The resin includes 5 wt % to 95 wt % of a first copolymer and 95 wt % to 5 wt % of a second copolymer based on the total weight of the resin. The first copolymer and the second copolymer together are 90 wt % or more of the total weight of the resin. The first copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms. The first monomer and the second monomer of the first copolymer are different. The first copolymer has an MFR of from 5 to 1000 g/10 minutes and a Tof 66 C. to 80 C. The second copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms. The first monomer and the second monomer of the second copolymer are different. The second copolymer has an MFR of from 0.

Abstract:

In a process for producing a mixture of cyclohexanone and cyclohexanol, a feed comprising cyclohexanone is contacted with hydrogen in the presence of a hydrogenation catalyst under hydrogenation conditions effective to convert part of the cyclohexanone in the feed into cyclohexanol and thereby produce a hydrogenation product containing cyclohexanone and cyclohexanol. A mixture of cyclohexanone and cyclohexanol is then obtained from the hydrogenation product.

International Classification:

C10M 107/10

US Classification:

585 18, 585506, 585509

Abstract:

Provided is a polyalphaolefin (PAO) fluid including a polymer of one or more Cto Calphaolefin monomers. The PAO has a viscosity (Kv) from 300 to 900 cSt at 100 C.; a viscosity index (VI) greater than 250; a pour point (PP) less than −25 C.; a molecular weight distribution (Mw/Mn) less than 2.0 as synthesized; a residual unsaturation (Bromine Number) less than 2.0; and a glass transition temperature Tless than −60 C. The PAO also has no crystallization peak as measured by differential scanning calorimetry and high thermal stability. A process to make and use the PAOs, including those having any combination of characteristics above is also provided. The PAOs are useful as synthetic base stocks and co-base stocks in lubricating oils, e.g., industrial lubes.

Abstract:

This disclosure relates to a composition for use as an additive for fuels and lubricants including a reductive amination product of a vinyl terminated macromonomer (VTM) based aldehyde. Optionally aldehyde is reacted with the amino compound under condensation conditions sufficient to give an imine intermediate, and the imine intermediate is reacted under hydrogenation conditions sufficient to give the composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde. A reductive amination method for making a composition for use as an additive for fuels and lubricants. The method includes reacting a VTM based aldehyde with an amino compound containing at least one —NH— group under condensation conditions sufficient to give an imine intermediate, and reacting the imine intermediate under hydrogenation conditions sufficient to give said composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde.
