Abstract: POROUS SHEET STRUCTURES AND A PROCESS FOR PRODUCING THEM FROM THERMOPLASTIC ELASTOMERS ARE PROVIDED WHEREIN ABOUT 100 PARTS BY WEIGHT OF A THERMOPLASTIC ELASTOMER ARE PROCESSED IN THE PRESENCE OF FROM ABOUT 60 TO ABOUT 150 PARTS BY WEIGHT OF SODIUM-HYDROGEN CARBONATE AND FROM ABOUT 3 TO ABOUT 15 PARTS BY WEIGHT OF AN ALIPHATIC ORGANIC CARBOXYLIC ACID HAVING A MOLECULAR WEIGHT OF FROM ABOUT 150 TO ABOUT 5000 AND AN ACID NUMBER OF AT LEAST 2.5 ON CALENDERS, PARTICULARLY HEATED CALENDERS, AND THE FILMS OBTAINED ARE FREED FROM SALT BY A SUBSEQUENT RINSING PROCESS. THE STRUCTURES THUS OBTAINED ARE EXCELLENT LEATHER SUBSTITUTES.

Abstract: COATED SUBSTRATES ARE PREPARED BY A PROCESS WHICH COMPRISES TREATING A SUBSTRATE MATERIAL WITH A CURABLE COATING COMPOSITION COMPRISING (A) A KETOXIME BLOCKED ISOCYANATE TERMIANTED REACTION PRODUCT OF A POLYOL WITH AN ISOCYANURATE POLYISOCYANATE, SAID REACTION PRODUCT HAVING A MOLECULAR WEIGHT OF FROM ABOUT 8,000 TO ABOUT 15,000, (B) A TERTIARY AMINOALCOHOL HAVING AT LEAST TWO HYDROXYL GROUP, OPITIONALLY IN THE PRESENCE OF (C) AN INERT ORGANIC SOLVENT, AND HEATING THE COATED SUBSTRATE MATERIAL TO TEMPERATURES OF FROM ABOUT 80*C. TO ABOUT 200*C. TO CROSSLINK THE CURABLE COATING COMPOSITION.
