| 摘要 |
The invention relates to monomers that are derived from a- and ß-amino-e-caprolactam and to polymers (e.g., homopolymers and copolymers) prepared from these monomers. In many embodiments, the a-amino-e-caprolactam or ß-amino-e-caprolactam is manufactured from a renewable starting material, for example, biomass. In one aspect, the invention relates to polyamide polymers that are prepared by the polymerization of a-amido-e-caprolactam monomer, ß-amido-e-caprolactam monomer, or a mixture thereof. In some embodiments, the monomers have the structures shown in Structure I and the polyamide polymers of the invention have the structure as shown in Structure II. |
