Poly(ether ester amides) consisting of 60% to 80% by weight of a polyamide block obtainable from the following monomers:20 to 40% by weight of caprolactam or aminocaproic acid30 to 50% by weight of 11-aminoundecanoic acid20 to 40% by weight of the adduct of hexamethylenediamine anddecanedicarboxylic acidthe total amount of these polyamide-forming monomers adding up to 100% by weight, and of 20 to 40% by weight of a polyether diol/dicarboxylic acid block obtainable from equimolar amounts of polyethylene glycol with an M.sub.n molecular weight of 400 to 2,000 and one or several saturated aliphatic dicarboxylic acids with 6 to 36 carbon atoms, methods for their synthesis, spunbonded nonwovens from these poly(ether ester amides) and the use of the poly(ether ester amides) for the heat sealing of textiles.
摘要:
Computer-readable medium storing a data structure for supporting persistant storage of a set of data, the data structure including: (a) at least an oldest version of the set of data in a first memory area the first memory area including at least one first tag for uniquely identifying the oldest version, and (b) at least a most recently updated version of the set of data in a second, distinct memory area, the second memory area including at least one second tag for uniquely identifying the most recently updated version. The invention also relates to a computer arrangement including a processor and such a computer-readable medium, as well as to a method of updating sets of data having such tagged-data structures.
摘要:
The invention relates to copolyamides containing caprolactam, lauriclactam, hexamethylene diamine adipate and hexamethylene diamine salt of an aliphatic dicarboxylic acid with a carbon chain of 9, 10, 12 or 13 carbon atoms. The copolyamides are useful as heat-sealing agents.
