Abstract
A process is disclosed for producing polyamide polymers from at least one circular atom component. The circular atom component, for instance, can comprise a fluid obtained from biomass or from an industrial waste stream, such as an industrial gas stream that would otherwise be released to the environment. Polyamide polymers, particularly high performance polyamide polymers, are produced not only containing large amounts of circular atoms but also with excellent mechanical and physical properties.
Claims24
A method for producing a polyamide polymer comprising:
- forming a polyamide polymer from a first monomer and a second monomer, the first monomer comprising a diamine, the second monomer comprising an aliphatic diacid comprising decanedioic acid, sebacic acid, dodecanedioic acid, or mixtures thereof, an aromatic diacid containing 8 to 20 carbon atoms, or mixtures thereof, wherein at least a portion of the first monomer is derived from a circular atom component, the circular atom component comprising a circular natural gas, and wherein the resulting polyamide polymer has a circular atom content of at least about 10% by weight.
A polymer composition comprising:
- a polyamide polymer formed from a first monomer and a second monomer, the first monomer comprising a diamine, the second monomer comprising an aliphatic diacid comprising decanedioic acid, sebacic acid, dodecanedioic acid, or mixtures thereof, an aromatic diacid containing 8 to 20 carbon atoms, or mixtures thereof, wherein at least a portion of the first monomer is derived from a circular atom component, and wherein the polyamide polymer has a circular atom content of at least about 10% by weight, the polyamide polymer being present in the polymer composition in an amount of at least about 15% by weight;
- optionally reinforcing fibers;
- a flame retardant composition;
- and
- a lubricant.
