摘要:
Hot melt compositions of the type according to the invention comprise up to 40% by weight of one or more isotactic homopolymer and/or copolymer waxes comprising the monomers ethylene and/or propylene and/or higher linear or branched alpha-olefins having 4 to 20 carbon atoms, which have been prepared by polymerization of the corresponding monomers in the presence of metallocene as catalyst, and at least 60% by weight of one or more amorphous, atactic polyalpha-olefins. Hot melt compositions of this kind are suitable for use as hot melt adhesives.
摘要:
The present invention relates to homopolymer and copolymer waxes which have been prepared by polymerization using metallocene compounds in the presence of hydrogen and have a melt viscosity of less then 100 mPas, measured at 170° C. As a result of their high thermal stabillty, these waxes display neither discoloration nor crosslinking reactions and are vary well suited for use in toners, for plastics processing, for masterbatches, for printing inks, surface coatings and melt adhesives.
摘要:
Cosmetic, pharmaceutical or dermatological preparations are described which comprise one or more homopolymer and/or copolymer waxes of the monomers ethylene and/or propylene. The homopolymer and copolymer waxes have a weight-average molecular weight Mw of less than or equal to 25 000 g/mol, a number-average molecular weight Mn of less than or equal to 15 000 g/mol, a molar mass distribution Mw/Mn in the range from 1.5 to 10 and have been obtained by metallocene catalysis. The copolymer waxes comprise, based on the total weight of the copolymer waxes, 0.1 to 30.0% by weight of structural units originating from the one monomer and 70.0 to 99.9% by weight of structural units originating from the other monomer.
