摘要:
The invention relates to a polyamide, the main chain thereof containing a chemically bonded amine selected from the group consisting of 2-methyl-1,5-diaminopentane and 1-amino-2-R-cyclopent-1-ene, wherein R represents a functional group that can react with an amino group to form an amide group. The invention also relates to a method for producing one such polyamide, and to fibres, films and moulded bodies containing the same.
摘要:
The invention relates to a polymer material (1) comprising a) a polymer (II) containing amide groups recurring in the main polymer chain and b) 0.01 to 5 wt % o titanium dioxide polymer (III) having an average particle size of d50 to 150 nm. The invention also relates to a polymer material containing fibres, textile fabrics and moulded parts.
摘要:
The invention relates to a method for producing polyamides, characterized in that the polymerisation of starting monomers or starting oligomers is carried out in the presence of at least one compound of formula (I), where R is a functional group R8 which has 1 to 4 identical or different amide-forming groups R7; R1 is H, C¿1?-C20 alkyl, cycloalkyl, benzyl, OR?6¿ where R6 is H, C¿1?-C20 alkyl, cycloalkyl, benzyl; R?2, R3, R4, R5¿ independently of each other are C¿1?-C10 alkyl; n is a natural number greater than 1, and the piperidine derivatives linked to R are identical to or different from the substituents, that is R?1, R2, R3, R4 and R5¿. Said polyamides can be used to produce thread, fibres, films, flat structures and moulded bodies.

摘要:
A process is disclosed for producing polyamides. The extracted water produced from polyamide extraction is concentrated up to an extract content of maximum 85 wt.% and is mixed with fresh lactam up to a 0.5-13 wt.% water content, at least one adiabatic stress relief being carried out during polymerisation.
