Abstract: Provided is a stable lignin-phenol blend for use in lignin modified phenol-formaldehyde resins comprising lignin in an amount between 10-80 wt %, phenol in an amount between 15-90 wt %, and a solubilizer in an amount between 0%-25 wt %.

Abstract: A method for removing ink and/or a foreign material different from ink from the surface of an article, wherein at least a part of the surface of the article comprises a polymer, the method includes: i) providing an ink imprinted article and/or an article having a surface covered at least partly by a foreign material different from ink; ii) contacting the article provided in step i) with an acid having a pKa in the range from ?10 to 7 having a minimum concentration of 1 wt.-% for solving the ink and/or the foreign material different from ink or their degradation products in the acid; iii) separating the acid and the therein dissolved ink- and/or foreign material different from ink or their degradation products from the article to obtain a deinked article and/or an article with a surface free from foreign material.

Abstract: The present invention is directed to a process for producing a modified olefin polymer having increased melt strength in an extruder. The process comprising the steps of: (A) contacting a stream comprising particles of an olefin polymer with a vapour stream of a functionally unsaturated compound in vapour phase thereby producing a first mixed stream; (B) passing the first mixed stream to an extruder; (C) melting the polymer particles of the first mixed stream in the extruder; (D) introducing a stream of a free radical generator either into the first mixed stream or into the extruder; and (E) extruding the first mixed stream and the free radical generator at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder.

Abstract: The present invention relates to wash oil for use as an antifouling agent in gas compressors, in particular in cracked gas compressors, including at least one compound according to formulae (II) with the moieties R2 and R3 are selected from a group of linear or branched C1-C20-alkyl, C3-C10-cycloalkyl and linear or branched C1-C10-alkyl substituted C3-C10-cycloalkyl and C6-C12 aryl and C1-C10-alkyl substituted C6-C12 aryl. The moieties can be interrupted by oxygen or nitrogen. The moieties can be functionalised with hydroxyl groups or amino groups. The moieties can be the same or different. The invention relates also to the use of such wash oil as anti-fouling agent.
