New shape memory polymer compositions, methods for synthesizing new shape memory polymers, and apparatus comprising an actuator and a shape memory polymer wherein the shape memory polymer comprises at least a portion of the actuator. A shape memory polymer comprising a polymer composition which physically forms a network structure wherein the polymer composition has shape-memory behavior and can be formed into a permanent primary shape, re-formed into a stable secondary shape, and controllably actuated to recover the permanent primary shape. Polymers have optimal aliphatic network structures due to minimization of dangling chains by using monomers that are symmetrical and that have matching amine and hydroxl groups providing polymers and polymer foams with clarity, tight (narrow temperature range) single transitions, and high shape recovery and recovery force that are especially useful for implanting in the human body.

The present invention relates to a modified epoxy acrylate and a method for producing the same, a photoresist composition and a method for producing the same, and a transparent photoresist formed from the photoresist composition. The modified epoxy acrylate is an epoxy acrylate modified with phosphate monomer which has a structure represented by Formula I ##STR00001## wherein, n is an integer selected from 1˜21, R is a short-chain carboxylic acid ester group having the structural formula ##STR00002##  in which p is a bivalent saturated or unsaturated carbon chain having 1˜10 carbon atoms, and the carbon chain is optionally substituted by alkyl, alkenyl, hydroxy, nitro or halogen. Since the phosphate can react with the multi-valence metal in substrates so as to connect the polymer onto the substrates firmly through covalent bonds, therefore the adhesion force is improved significantly and the protective function of the tranparent photoresist is improved accordingly.
