20080214779 | Polymers with pendant alkyl chains - A hydrophobic polymer made by incorporating alkyl chains pendant to the main backbone of the polymer. Alkyl chains of from about 6 to over 22 carbons are fatty compounds well known in the art. The present invention allows linking such chains from commercially available starting materials. It is well known that starting materials such as tallow diamine or ethoxylated tallow amine typically contain a mixture of chain lengths with varying degrees of branching and unsaturation. The unsaturated positions in the final polymer can be made to cross-link in the presence of a catylst and UV light to increase the hardness and reduce the effect of heat and solvent borne exposures. The present invention can be a replacement to current monomers or additive to common polymers to replace or modify the current polymers to alter the properties of the polymer or economics. The present invention adds the known benefits of fatty compounds to common polymers such as hydrophobicity, or alter the HLB (hydrophilic lipophilic balance) of polymeric surfactants. The present invention is directed primarily to urea, urethane, and urea-urethane linkages, but is expected to be useful in the incorporation of pendant alkyl structures in other types of polymers that use an amine, carboxcylic acid or alcohol group to form the linkage. Other polymer types which can utilize this invention that are obvious to one skilled in the art include, but are not limited to the following: polyamide, polyester, polycarbonate, polyether, polysiloxane, epoxy. | 09-04-2008 |

20090264651 | Biological Buffers with Wide Buffering Ranges - Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability. | 10-22-2009 |
