Producing polyamide-6 nanocomposite used in packaging and automotive industry, involves dissolving solid epsilon-caprolactam monomer in water, and adding dissolved material with acetic acid and sodium clay or organoclay

NOVELTY – Producing polyamide-6 nanocomposite involves dissolving solid epsilon -caprolactam monomer in 3.0-10.0 wt.% water and then adding the dissolved material with 5.0-15.0 wt.% acetic acid and 0.5-10.0 wt.% sodium clay or organoclay. The obtained material with corn is kept in a reactor in nitrogen gas atmosphere and then the obtained material is homogenized. The homogenized material is stirred at 80-100 degrees C and at a speed of 20-50 revolutions per minute. The stirred material is heated at 230-270 degrees C for 3-5 hours and at 3-6 kilogram-force per square centimeter. USE – Method for producing polyamide-6 nanocomposite used in packaging and automotive industry (all claimed). ADVANTAGE – The method enables to produce polyamide-6 nanocomposite without requiring catalyst. DETAILED DESCRIPTION – Producing polyamide-6 nanocomposite involves dissolving solid epsilon -caprolactam monomer in 3.0-10.0 wt.% water and then adding the dissolved material with 5.0-15.0 wt.% acetic acid and 0.5-10.0 wt.% sodium clay or organoclay. The obtained material with corn is kept in a reactor in nitrogen gas atmosphere and then the obtained material is homogenized. The homogenized material is stirred at 80-100 degrees C and at a speed of 20-50 revolutions per minute. The stirred material is heated at 230-270 degrees C for 3-5 hours and at 3-6 kilogram-force per square centimeter. The heated material is depressurized for 2 hours at -700 to -500 millimeter of mercury. The obtained material is removed from the reactor and then cooled, washed and dried at 100 degrees C.
