Resist reactive-ion etching (RIE) was performed with a totally modified Tegal Model 400 plasma reactor. Ion-milling (IM) was accomplished with a Veeco three inch system. All resist RIE and IM etch rates are measured versus the rate of Si02 and PMMA as outlined above. 

The transport reactor appears ideal for efficiently regenerating the sorbent. The key to the successful operation of this unit is the attrition-resistant, reactive, and regenerable RTI-3 sorbent. Recently, the RTI-3 sorbent has been scaled up to a production level of 10,000lbs by Siid-Chemie Inc. (SCI).

A chemical reaction is a change in which at least one substance changes its composition and its set of properties. The characteristic ways in which a substance undergoes chemical reaction, or fails to undergo chemical reaction are called its chemical properties. Examples of chemical properties are flammability, rust resistance, reactivity, and biodegradability. 

Specifically, PVC blends with polyethylene, polypropylene, or polystyrene could offer significant potential. PVC offers rigidity combined with flammability resistance. In essence, PVC offers the promise to be the lowest cost method to flame retard these polymers. The processing temperatures for the polyolefins and polystyrene are within the critical range for PVC. In fact, addition of the polyolefins to PVC should enhance its ability to be extruded and injected molded. PVC has been utilized in blends with functional styrenics (ABS and styrene-maleic anhydride co-and terpolymers) as well as PMMA offering the key advantage of improved flame resistance. Reactive extrusion concepts applied to PVC blends with polyolefins and polystyrene appear to be a facile method for compatibilization should the proper chemical modifications be found. He et al. [1997] noted the use of solid-state chlorinated polyethylene as a compatibilizer for PVC/LLDPE blends with a significant improvement in mechanical properties. A recent treatise [Datta and Lohse,... 

Other reusable finishing products are thermoplastic hotmelt grades that can be remelted. Because of this thermoplastic behavior they are not suitable for washable applications. To achieve wash resistance, reactive hotmelt systems should be used, being curable using humidity or UV, though not reusable.

The spotting tack and/or the heat resistance of elastomeric polyurethane adhesives may he extended by adding resins (alkyl phenolic, epoxide, terpene phenolic, coumarone) or polymers (low crystallizing polyurethane, acrylic, nitrile ruhher, chlorinated ruhher, acetyl cellulose) (Penczek and Nachtkamp 1987) with low miscihility with the polyurethane. To improve adhesion together with heat resistance, reactive alkyl phenolic resins, chlorinated rubber, or other chlorine-containing polymers can be added.
