The present invention relates to the discovery of new class of linear and multiarmed hydrolysable linkers and cross linkers for use in the synthesis of biodegradable polymers such as, polyesters, polyurethanes, polyamides, polyureas and degradable epoxy amine resin. The linear and multiarmed hydrolysable linkers of the present invention include symmetrical and/or unsymmetrical ether carboxylic acids, amines, amide diols, amine polyols and isocyanates.
