The removal of oxygen prevents oxidation of the filaments in the tube. With reference to FIG. 1, numeral 14 denotes the housing of an electrostatic copier. A plurality of copier components are mounted inside the housing. The components coact to produce a series of processing steps which collectively form the well-known electrophotographic process.

6.1.2 Wet-process Two-component System. With this system, plasticizer is mixed into the polymer before extrusion. Phase separation between the plasticizer and the polymer occurs in microscopic regions within the molten bulk during cooling after extrusion, and the pores are formed by removing the plasticizer.

For polymers that degrade prior to melting, the polymer is spun from a solution; if the solvent is evaporated, the process is termed dry spinning; if the solution is coagulated in a nonsolvent bath, the process is termed wet spinning. Removal of the spinnerette from the wet spinning coagulation bath is the innovation known as dry-jet wet spinning.

In contrast with thermoplastics, thermosetting plastics (also referred to as thermosets) remain in a permanent solid state after curing. Polymers in thermosetting materials cross-link during a curing process that is induced by heat, light, or suitable radiation. This curing process forms an irreversible chemical bond.
