Described herein is a method for producing a PU foam insole, including the following steps of: (1) pouring the raw materials used to form a PU foam into a mould, reacting to obtain a PU sheet, where the height of the mould cavity is from about 1.0 to about 1.6 times of the total thickness of two finished insoles; (2) splitting the PU sheet into two halves in the horizontal direction to obtain two pieces of PU insole material, where one surface of the material has open pores, and the other surface of the material has a skin; and (3) attaching a piece of fabric onto the surface having open pores of the material obtained in step (2). Also described herein is a PU foam insole produced by the method.

The invention relates to a silyl-containing polymer that is used, together with a tackifying resin to form an adhesive composition capable of storing and delivering drugs to the skin of a user. Typically the composition is formed into a patch which shows excellent adhesion to the skin even when drugs and other additives are dissolved into the composition.

The present invention relates to a multi-aziridine compound having: a) from 2 to 6 of the following structural units (A): whereby R′, R″ are as defined herein m is an integer from 1 to 6; b) one or more linking chains wherein each one of these linking chains links two of the structural units A; and c) a molecular weight in the range from 840 Daltons to 5000 Daltons. The multi-aziridine compound can be used for example for crosslinking of for example carboxylic acid functional polymers dissolved and/or dispersed in an aqueous medium.
