Appl. No.:

10/973128
Inventors:

Tina Nataniel - Saint Charles IL, US

Assignee:

Henkel Corporation - Gulph Mills PA
International Classification:

C08G 69/26
US Classification:

5283393, 528324, 528314, 528345
Abstract:

Polyamides useful as hotmelt adhesives and having improved resistance to hydrocarbons such as gasoline are obtained by reacting a) an acid component containing at least one Cto Caliphatic dicarboxylic acid and b) an amine component containing at least one straight chain alkylene diamine having from 2 to 8 carbon atoms and at least one heterocyclic secondary diamine. The amine component may optionally also contain at least one branched chain alkylene diamine having from 3 to 10 carbon atoms and/or at least one Cto Cdimer amine.

Appl. No.:

12/839766
Inventors:

Tina Nataniel - Saint Charles IL, US
Dwight D. Heinrich - Aurora IL, US
Assignee:

Henkel Corporation - Rocky Hill CT
International Classification:

C08G 69/26
B32B 37/12
US Classification:

1563318, 528335
Abstract:

Solvent-resistant polyamides having an exceptionally desirable combination of properties, including good cold flexibility, excellent impact resistance and high heat resistance are obtained by reacting a) an acid component comprising at least one Cto Caliphatic dicarboxylic acid and b) an amine component comprising at least one alkylene diamine having from 2 to 14 carbon atoms, at least one polyoxyalkylene diamine containing at least one polyoxytetramethylene block, and at least one polyoxyalkylene diamine that does not contain a polyoxytetramethylene block. Such polyamides are particularly useful for molding and bonding applications, such as, for example, in the filter industry, especially articles that are to be used in applications involving organic solvents, fuels or oils.

International Classification:

C08G 6926
C08G 7310
C08L 7706
US Classification:

528310
Abstract:

A polyamide resin comprising the reaction product obtained by the reaction of an acid component comprised of a major concentration of a dimer acid and minor concentration of a monobasic acid and an amine component comprised of a major concentration of a short-chain alkylenediamine, a first minor concentration of a medium-chain alkylenediamine and second minor concentration of a polyoxyalkylene diamine having a molecular weight greater than about 500 is provided. The polyamide resin is used to form a blend of containing the polyamide in a major amount by weight and a first minor amount by weight of a polar wax and a second minor amount by weight of a polyolefin elastomer. The composition is used to reinforce a footwear upper, e. g. as a print on box toe material.
