Synthesis and characterization of polydimethylsiloxane-polyamide segmented copolymers
The polyamide poly(ε-caprolactam) or "nylon 6" is a very important fiber forming polymer which finds many applications in the carpet industry and elsewhere due to the very high strength of this fiber. However, a major drawback is its hydrophilicity. This feature influences both the surface and bulk …
