  • Low Viscosity Transparent Polyamide
    Publication number: 20190375936
    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.

  • Polyamides
    Patent number: 7163996
    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.
