## Abstract Ring opening metathesis polymerization derived poly(norbornene) films and aggregates were crosslinked via photo chemically induced thiolβene chemistry using a multifunctional thiol and the double bonds present in the polymer backbones. The presented method was illustrated by the descrip
## Abstract **Summary:** A phenolic group containing hyperbranched polyester (HBP) was synthesized and employed as chain transfer agent in cationic photopolymerization of a biscycloaliphatic epoxy monomer (**CE**). The epoxy group conversion increases by increasing the amount of HBP in the photocur
## Abstract A new concept to build shape memory polymers (SMP) combining outstanding fixity and recovery ratios (both above 99% after only one training cycle) typical of chemically crosslinked SMPs with reprocessability restricted to physically crosslinked SMPs is demonstrated by covalently bonding
