Each year about 50 Million tons polymer is processed to fibers worldwide [1]. Polymeric fibers are manufactured into all sorts of daily as well as industrial goods [2, 3]. The most prominent materials are thermoplastic among which poly(ethylene terephtalat) (PET), polyamides (PA) and polypropylene (PP) make up the largest fraction [4]. Other thermoplastic polymers such as poly(vinylidene fluori...

The potential of bio based plastics for replacement of petrochemical plastics is 90%, corresponding to 240 million tons per year.1 Bio-based materials such as polynucleotides, polyamides, polysaccharides, polyoxoesters, polythioesters, polyanhydrides, polyisoprenoids and polyphenols are potential candidates for substitution of synthetic plastics.2 Polyhydroxyalkanoates (PHAs), belonging the gro...

Until now, our discussion of polymers has been limited to functional groups containing carbon, hydrogen, and oxygen. In this column, we begin covering that have nitrogen as well. We review the structures bonding characteristics atom, then examination spectra organic with a very important class polymers: polyamides.

Pyrrole-imidazole (Py–Im) polyamides are a class of programmable DNAminor groove binders capable of modulating the activity of DNA-binding proteins and affecting changes in gene expression. Estrogen receptor alpha (ERa) is a ligand-activated hormone receptor that binds as a homodimer to estrogen response elements (ERE) and is a driving oncogene in amajority of breast cancers.We tested a selecti...
