An assembly of timepiece parts assembled together with an adhesive at a temperature TA and to be repositioned when the adhesive is at a temperature TC. The adhesive includes a formulation, which at TC includes a mixture of polymer chains with pendant diene units X and coupling molecules including two dienophile end groups Y, wherein the X units and the Y groups are arranged to react with one another and to bond together with the Diels-Alder reaction at a temperature TDA and to regenerate with the retro-Diels-Alder reaction at a temperature TRDA, at TA forms a three-dimensional network, in which the polymer chains are linked to one another by the coupling molecules with the Diels-Alder reaction, where TA
在温度 TA 下用粘合剂组装在一起的钟表零件组件,当粘合剂处于温度 TC 时可重新定位。粘合剂包括一种配方,该配方在温度 TC 时包括具有下垂二烯单元 X 的聚合物链和包括两个亲二烯端基团 Y 的偶联分子的混合物,其中 X 单元和 Y 基团相互反应,在温度 TDA 时通过 Diels-Alder 反应粘合在一起,在温度 TRDA 时通过逆 Diels-Alder 反应再生、在 TA 温度下形成三维网络,其中聚合物链通过偶联分子与 Diels-Alder 反应相互连接,TA
