The present invention concerns copolymers a process for their preparation and their use in producing ionic conduction materials. According to the invention the copolymer consists of monomer units of formula -CH2-O-CHR-CH2-O- (I) and monomer units of formula -CH2-CHR'-O- (II) in which: R is a hydrogen atom a linear or branched alkyl radical having 1 to 8 carbon atoms or a CH3(-O-CH2-CH2)n-O-CH2- radical in which 1 <= n <= 10; R' is an aliphatic radical showing insaturation capable of undergoing polymerization by the radical route and inert in cationic polymerization conditions. Said copolymers can be obtained by cationic polymerization of suitable oxirane and dioxolane. Application in the …

Why it's free to use
- Filed July 7, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 7, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
