【Abstract】 The reinforcing effects of various Aluminum Carboxylates on crosslinked polyethylene were studied. It was found that the reinforcing effect of Aluminum acrylate is superior to those of the other Aluminum derivatives. An increase of 50% tensile strength of crosslinked polyethylene can be obtained by adding 20phr of Aluminum acrylate. The measurement of specific surface area showed that the greater the specific surface area of reactive filler, the better the reinforcing effect will be. Utilizing methods such as swelling measurement, Sox-hlet extraction, DSC and dynamic mechanical measurement, we have investigated the reinforcing mechanisms of Aluminum acrylate on crosslinked polyethylene.lt seems that the reinforcing effects may be resulted from the crosslinking and grafting reactions between polyethylene and Aluminum reactive filler.更多还原
