Process for frontal polymerization of cationically polymerizable monomers
The invention relates to a process for free radical-induced cationic frontal polymerization of cationically polymerizable monomers using a combination of at least one cationic polymerization initiator and at least one activator for said at least one initiator, characterized in that benzopinacol is used as said activator.
THERMADAPT SHAPE MEMORY POLYMER AND APPLICATION METHOD THEREOF
A preparation method of thermadapt shape memory polymers includes: (1) synthesis of pendant hydroxyl groups functionalized epoxy oligomer using epoxy resin and alcohol amine; (2) synthesis of alkoxyl groups terminated silane crosslinking agent by isocyanate silane coupling agent and diamine; (3) crosslinked shape memory polymers were prepared by condensation reaction of pendant hydroxyl groups functionalized epoxy oligomer and alkoxyl groups terminated silane crosslinking agent. The thermadapt shape memory polymers show high glass transition temperatures and high tensile strength. The original shape of thermadapt shape memory polymers can be reconfigured to a new permanent shape as needed, and thus effectively solving the bottleneck problems of reprocessing or reshape in the traditional crosslinked polymers once after molding. The thermadapt shape memory polymers are suitable for smart materials based on shape memory polymers with complex three-dimensional permanent shapes, and showing unfolding or folding behaviors along with convert to three-dimensional structures under heat stimulation.
