  • Polymer laminar composite having improved layer adhesion
    Publication number: 20110236690
    Abstract: 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.

  • Polymerizable dental material based on chromophoric xerogels
    Patent number: 6833394
    Abstract: Dental materials based on polymerizable binders, which contain at least one chromophoric xerogel of the formula I: (SiO2)a(SiO1.5-Sp-X-CG)(MenOm)b  (I) in which Me represents a main-group metal of the 2nd to 3rd main groups or a transition metal of the 4th sub-group of the periodic table of elements; n being equal to 1 or 2, m being equal to 1 or 2 if n is equal to 1 and m being equal to 3 if n is equal to 2; Sp is a C1 to C10 alkylene radical or C2 to C10 oxyalkylene radical with 1 to 4 oxygen atoms or is absent; X is a compound group, such as CO—O, O—CO, CO—NH, NH—CO, O—CO—NH, NH—CO—O, NR, O or S or is absent, R being hydrogen or a C1 to C5 alkyl radical; CG is a chromophore; a is an integer from 0 to 20 and b is an integer from 0 to 5.
