    摘要: The present invention relates to an innovative polymerization technique for (meth)acrylates or styrenes, in which a special base with imine structure is added as a latent initiator, and the polymerization can be initiated without adding a coinitiator, at high temperatures. With this new and selectively employable technique it is also possible to produce high molecular weight poly(meth)acrylates having in some cases narrow molecular weight distribution. Furthermore, employing this new polymerization technique, a wide variety of different polymer architectures is available, such as block, star, or comb polymers.

    摘要: The present invention provides a polymer laminar composite including a first layer and a second layer at least partially in contact with the first layer. The first layer includes a polyurethane polymer which is the reaction product of a polyisocyanate A) and/or a polyisocyanate prepolymer B) with an at least difunctional, isocyanate-group-reactive compound C) and a monomeric, monofunctional aromatic alcohol. The second layer includes polymeric thiophene of the formula (I), substituted at the 3 and/or 4 position: and polystyrene sulfonate. 2-Hydroxymethyl-3,4-ethylene dioxythiophene is preferably used for the first layer and poly(3,4-ethylene dioxythiophene) for the second layer. The invention further relates to a process for producing such a laminar composite, as well as an electromechanical converter containing this laminar composite.
