IN SITU COMPATIBILIZATION OF LDPE/NYLON-6 BLEND USING LOW MOLECULAR WEIGHT INTERFACIAL AGENT AS A CHEMICAL COMPATIBILIZER

Received Date: 31 March 1997

In situ compatibilization of low density polyehylene (LDPE) (30%) and nylon-6(70%)blends through one-step reactive extrusion using t-BuOOH as an initiator and low molec-ular weight interfacial agents as compatibilizers was studied. The compatibilizer containeda long chain bydrocarbon, double bond and two polar functional groups which was capableof reacting with both LDPE and nylon-6 in the presence of initiator to form a copolymerat the interface of the two polymer phases. The extruded blends exhibited significant enhancement in their compatibility based on morphological,thermal analysis and mechanical studies.The effect of the hydrocarbon chain length and structure of the functional group of the compatibilizer was also examined.It was found that blends prepared by using the compatibilizer containing longer hydrocarbon chain and amide group had better mechanical properties.
