摘要:
Ester-modified polyamides containing of from 50 to 80% by weight of --HN--(CH.sub.2).sub.5 --CO units are obtained by reaction of .gamma.-caprolactam and mixtures of dicarboxylic acids, primary diamines and polyalkylene glycols and are suitable inter alia as hot melt adhesives and for the elastification of thermoplastic materials.
摘要:
An adhesive consisting substantially of a modified olefine polymer, a chlorinated olefine or diene polymer, an alkylated polyphenyl, an aromatic polynitroso compound and an organic solvent or solvent mixture.
摘要:
Storable polychloroprene adhesives can be produced by polymerizing chloroprene in a manner known per se in the presence of a dialkylxanthogen disulphide reacting 50 to 90% of the monomer and dissolving the polymer thus obtained in an organic solvent to obtain viscosities in the range of 10 to 100 poises.
