Ethers blending index

EP 323142 (European) 1989 Ternary polyether ketone blend wire insulations Pirelli General PLC, UK CK Alesbury, RJ Murphy Formulation shows excellent stress craze resistance, flexibility and flame resistance Blends of polyarylene ether ketones, polyether imides and polyfimide siloxanes) were coated onto wire for solvent resistance, O index and abrasion resistance. Blends without siloxane-imide copolymer did not meet these properties... 

Poly(vinyl ethers) have extensive uses as nonmigrating tackifiers in adhesives and particularly pressure-sensitive tapes and labels, as viscosity-index improvers in lubricants and as plasticizers in coatings, films, and elastomers. They are available and used in dry state, solution or as blends with a wide variety of compatible polymers and copolymers. 

In Germany, however, bioethanol will mainly be used as low blend of bioethanol and petrol (E5, ElO) and for the production of ETBE (ethyl-tertiary-butyl-ether). Similar to methyl-tertiary-butyl-ether (MTBE), ETBE is used to enhance the octane index and improve knock-resistance and combustion properties of gasoline." It is less challenging to handle, does not induce evaporation of gasoline and does not absorb moisture like ethanol does. ETBE is produced by reacting ethanol and isobutylene via acid catalyst ...
