A new chemical vapor reaction system is described. Instead of ECR where electrons can move as independent particles without interaction, a mixed cyclotron resonance is a main exciting principal for chemical vapor reaction. In the new proposed resonance, the resonating space is comparatively large so that a material having a high melting point such as diamond can be deposited in the form of a thin ...

The present invention is a process of making strap using both post consumer and non-post consumer PET of wide distribution intrinsic viscosity (IV) through direct solid state polymerization in a non-peletized state to produce PET with an increased, heterogenous IV suitable for high performance strap extrusion. The process increases the IV of post-consumer resins, consisting principally of polyethy...
