Chemical modification of nylon 6 by organoacetoxy‐ and ethoxysilanes

摘要

AbstractChemical crosslinks were introduced in nylon 6 filament by means of organoacetoxy‐ and ethoxysilanes in benzene under anhydrous conditions. A comparison of the relative reactivities of these silanes toward nylon was made on the basis of the weight add‐on calculated from silicon analysis. Application of acetoxysilanes on preswollen nylon caused an increase in the breaking stress and extensibility. However, a decrease in the initial modulus, birefringence, and moisture regain was observed. An improvement in the thermal stability has also been observed in the crosslinked samp
