Ethylene interpolymers

Other thermoplastic elastomer combiaations, ia which the elastomer phase may or may not be cross-linked, include blends of polypropylene with nitrile (30,31), butyl (33), and natural (34) mbbers, blends of PVC with nitrile mbber (35,36), and blends of halogenated polyolefins with ethylene interpolymers (29). Collectively, thermoplastic elastomers of this type ate referred to herein as hard polymer/elastomer combinations. Some of the more important examples of the various types are shown in Table 3.

Random block copolymers of polyesters (hard segments) and amorphous glycol soft segments, alloys of ethylene interpolymers, and chlorinated polyolefins are among the evolving thermoplastic elastomers. 

A variety of materials are used when manufacturing a cover, including reinforced concrete, steel, aluminum, polypropylene, chlorosulfonated polyethylene, or ethylene interpolymer alloys. There are several factors that affect a reservoir cover s effectiveness and thus its ability to protect the stored water. These factors include the following ... 

Ethylene interpolymer alloys are used for fuel, fertilizer or transformer oil containment.

Exxon Qiem. (Stehling et al. 1995) disclosed blends of linear ethylene interpolymer that comprised m-LLDPE and VLDPE (Appendix, Table 18.12). The polymers prepared using metallocene catalyst had narrow MWD, = 1-3, and a narrow chemical composition distribution (CCD), expressed by its index, CDBl > 50 %, and measured by TREE. The components could have the same MW but different BC, the same BC but different MW, or BC that increase with MW. The blends had either > 3 or CDBI < 50 % or both these...

Blends based on halogen-containing polymers are also significant [30-32]. Those based on halo-genated polyolefin/ethylene interpolymer blends are claimed to be single-phase systems [32]. They are often used where solvent and fire resistance is important. PVC/nitrile rubber/dioctyl phthalate blends are used in similar applications and also in footwear [30-32].
