Block copolymers early research

The homo- and copolymerization of methacrylates and acrylates and the synthesis of block copolymers is also reported [108], Recently, it is reported that new organometallic compounds (late metals) also produce ethylene/MMA copolymers [54, 55]. The development of polymerization catalysts incorporating late transition metals is a promising area of research, since late metals are typically less oxophilic, and thus more functional group tolerant, than early metals. Examples of the functional group tolerance of late metals in insertion-type reactions include reports on Ru, Rh, Ni, and Pd catalysts. 

In the early 1980s, Sony Corporation initiated research on polymer lithium-ion batteries. At that time there was no such term as "polymer lithium-ion battery." The main idea is to use a block copolymer of poly vinylidenefluoride-hexafluoro propylene (P(VDF-HFP) as a gel carrier for the organic electrolytes. The composition of this polymer lithium-ion battery is shown in Figure 14.7 [3]. Later, Samsung Corporation coated a polymer on the traditional separators to act as a host for the organic electrolytes to prepare gel polymer electrolytes. Sanyo Corporation added precursors of PEO and plasticizers (organic...
