| Abstract: | Poly lactic acid/organomontmorillonite intercalation nanocomposites were synthesised by in-situ intercalation polymerization with organomontmorillonite from Xiazijie Sodium-base montmorillonite and lactide.The polymerization techniqued which included polymerization vacuum,catalyst dosage,polymerization temperature,polymerization time and OMMT dosage were studied. It was shown that the optimum parameters were as following:the vacuum was 0.085 MPa,the catalyst dosage was 0.5% of lactide mass,the polymerizatio... |
