Title:
光活性化された形状記憶共重合体
Document Type and Number:
Japanese Patent JP2008516051
Kind Code:
A
Abstract:
The present discovery uses monomers which contain reversible photo-crosslinkable groups in addition to primary polymerizable groups. The mechanical properties of these materials and the reversibility of the photo-activated shape memory effect demonstrate the effectiveness of using photo-irradiation to effect change in modulus and shape memory effect. In the preferred embodiment the reaction mixture includes a photo-reactive monomer comprising a photo reactive group and a polymerizable group; a second monomer, which is more preferably a mixture of monomers, which are acrylate based; a multi-functional crosslinking agent, preferably 1,6 hexanediol diacrylate (HDODA); an initiator, preferably a free radical initiator; and a fifth, optional, component which is a modifying polymer. The mixture of the second monomer, crosslinking agent, and initiator comprise the base polymer matrix into which the photo-reactive monomer is incorporated. The polymeriziable group of the photo reactive monomer allows the photo reactive monomer to polymerize with the base polymer matrix.
