Abstract: A low viscosity and transparent polyamide and a method for making the same. The transparent polyamides comprise the reaction products of a fully hydrogenated dimer-acid; a second linear, saturated dicarboxylic acid; an alkylene diamine; a dipiperidine; optionally a second diamine different from the alkylene diamine; and optionally additives. The polyamides have low molten viscosity and high light transmittance.

Abstract: The present invention is directed to polyamides that are crosslinkable in the presence of water having desirable properties including long open time, good adhesion and cold flexibility. Notably, the polyamides of the present invention are suitable for structural and semi-structural bonding applications utilizing a hot melt process, roll coater or bead extrusion process.

Abstract: The invention relates to the use of polyamides on the basis of reaction products from at least one dimeric fatty acid, at least one aliphatic dicarboxylic acid having 6 to 24 C atoms and aliphatic, cycloaliphatic and/or polyether diamines, wherein the quantities of amine components are selected so that primarily terminal amine groups are contained therein, and the polyamide comprises an amine count from 2 to 20 mg KOH/g to produce molded parts in the low pressure injection molding method.

Abstract: The reaction of diner acids, C10-C20 dicarboxylic acids, and alkylene diamines having from 2 to 8 carbon atoms provides polyamides having good oil and solvent resistance, high heat resistance, flexibility, and relatively low melt viscosities.

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 C6 to C22 aliphatic 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.

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 C6 to C22 aliphatic 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 C24 to C48 dimer amine.
