Title:
無色・高透明且つ形状記憶更新が可能な形状記憶架橋ポリエステル樹脂およびその製造方法
Document Type and Number:
Japanese Patent JP7462931
Kind Code:
B2
Abstract:
To provide a method of overcoming problems such as being impossible "to remove the memory shape, furthermore to update the memory", furthermore "being difficulty in designability because ordinary epoxy resin is a colored material of yellow or brown." due to the use of chemical crosslinking accompanying a permanent life in almost cases, when preparing the conventional shape memory resin caused by recovering a shape of macroscopically undeformed state of a polymer material, accompanying to recover to a stable network structure in the undeformed state, when transforming to a rubber state by imparting energy by heating.SOLUTION: The shape memory crosslinked polyester resin 1 includes a polymer main chain 6 containing an ester bond 2 at multi-points, a multipoint covalent cross-linking portion 4 containing a free OH group 3, and an ester exchange catalyst 5.SELECTED DRAWING: Figure 10
