When you render, make sure you render to a format that supports alpha channels, for instance numbered TIF or TGA.
To import it into AE, simply point to the first file (myrender0001.tif) and check the sequence box at the bottom of the dialog. You may get a popup asking a bit further about the alpha channel, if you have rendered with 3dsmax with the environment bgcolour black then the matte is the black, select that and now you can just use the sequence, the background will be removed. For better results I guess you should use an option such as the one in 3dsmax called "don't antialias against background"
