Mono-olefinic rubber

A wide range of synthetic rubbers are available on the market that display elastic properties similar to those of natural rubber. Some types of rubbers of industrial interest are classified as (1) diene rubbers, (2) mono-olefinic rubbers, (3) silicones, and (4) fluoro-olefinics. 

Mono-olefinic rubbers are fully saturated elastomers obtained by copolymerization of linear mono-olefins. In general, the cross-linking process is... 

Tphe major objective of this work was to understand better the effect - of heavy metals in autoxidation reactions in view of the importance of trace metals in oils, fats, rubber, plastics, and other materials. Because of our interest in the stability of polyolefins such as polyethylene and polypropylene the major model substance used was 2,6,10,14-tetramethyl-pentadecane. With its four tertiary C—H bonds it is a suitable model for either polypropylene or branched polyethylene. Hexadec-l-ene was also used since its mono-olefinic character could be typical of some residual unsaturation in polyethylene. N-alkylamides served as model substances for polyamides, and a few experiments were also carried out with methyl linoleate. While studying the causes of initiation of the autoxidation of these substances we observed that certain compounds were catalysts at low concentrations but became inhibitors at higher concentrations. The phenomenon was called catalyst-inhibitor conversion. ... 

Isoprene polymers, both of low molecular weight such as squalene, and of high molecular weight such as natural rubber and gutta percha also differ from mono-olefins in that intramolecular reactions can occur because of the multiple unsaturation and the short distances between the double bonds. For such materials it has been shown that a diperoxide-hydroperoxide structure is formed which Holland and Hughes (1949) proposed as ... 

Substituted and unsubstituted bi- or multi-cyclic mono-, di- or multi-olefins, i.e. containing condensed rings at least one of which contains a double bond. Norbomene is homopolymerised commercially whilst, as previously mentioned, ethylidenenorbomene and dicyclopentadiene are used as the cure site monomer in EPDM rubbers.

The traditional role of carpeting plus rubber or PVC mats as the flooring surface is being challenged by noncarpet alternatives (1) based on olefinic TPEs capable of a more utilitarian function (e.g., washable) and decorative look (colors, printed patterns, and molded-in decorative effects). Polypropylene carpet floor surfaces are increasing their share of the market (13), further supporting the drive for mono-material construction based on polyolefins.
