Abstract: The invention concerns a sound insulation element (10), that utilizes a strong force-network as a principle energy dissipating mechanism, whereat the strong force-network is generated through complex interactions of solid particles (14) in a granular system, which leads to formation of maximal number of interconnecting pairs-of-forces according to 3rd Newton's Law, whereat said strong force-network is realized by using a granular material (12) made from at least one solid material with a specific skewed multimodal particles-size-distribution, comprising a granular material (12) consisting of particles (14), and a supporting structure (40) having at least one cavity (42), whereat the at least one cavity (42) is filled with particles (14) of the granular material (12).

Abstract: The invention relates to a thermoplastic polymer mixture containing m, m representing a natural number higher than 1, polymers Pn wherein n represents a natural number between 1 and m, and at least one recurring functional group contained in the Pn polymer chain, said group(s) having the structure —(R1)x—C(O)—(R2)y— wherein x and y independently represent 0 or 1, and x+y=1, and R1, R2 independently represent oxygen or nitrogen linked into the main polymer chain. The polymers Pn differ in terms of at least one characteristic related to molecular weight. The polymer mixture has a number average molecular weight Mn(P)1, a weight average molecular weight Mw(P)1, a Z average molecular weight Mz(P)1, a heterogeneity index Mw(P)1/Mn(P)1, and a molecular weight Mp(P)1 defined according to DIN 55672-2 in hexafluoroisopropanol as an elution agent.
