Abstract: The present document relates to a method of performing acoustic scanning probe microscopy for imaging structures underneath a substrate surface, comprising: applying an acoustic input signal to the substrate having a frequency above 1 gigahertz, detecting a return signal, and analyzing the return signal for obtaining information on the embedded structures. The step of applying the acoustic input signal comprises applying a plurality of acoustic signal components which each include a selected frequency. The step of detecting includes detecting a response signal for each of the plurality of acoustic signal components. The frequencies are selected such that the components provide a composite signal being a pulse signal of limited time duration. The invention is further directed at a scanning probe microscopy system and a computer program product.

Abstract: A process for increasing the chemical resistance of a polymeric composition is provided. The method includes a step of blending: a) the (meth)acrylic polymer AP1 and b) a copolymer CP1. The copolymer CP1 includes at least 41 wt % of vinyl aromatic monomer units by weight of the copolymer CPI. The polymeric composition includes at least 5 wt % of the copolymer CP1, by weight of the polymeric composition. A chemical resistance of the polymeric composition is better than a chemical resistance of the (meth)acrylic polymer AP1 without CP1. Chemical resistance is measured by a time to crack at 120° C. when subjected to an outer radius bending strain of 75% and wetted with a cloth soaked in isopropanol 99%.
