The present invention provides compounds having both a pendent ether group and a pendent ester group that are useful as plasticizers for polymer resin and methods of making and using the same. In one embodiment of the invention, compounds according to the invention are formed by converting at least one, but not all, of the hydroxyl groups of a polyol having three or more hydroxyl groups (e.g., gylcerol, pentaerythritol or dipentaerythritol) to a pendent ether group to form a partially-etherized intermediate, and then converting at least one of the remaining hydroxyl groups in the partially-etherized intermediate to a pendent ester group.
