摘要：

A one-step acrylated polyurethanes prepolymers synthesis by reactive extrusion and bulk reaction is discussed. These oligomers are obtained by a simultaneous reaction of MDI, polycaprolactone and hydroxyethyl-acrylate. In order to obtain a high reaction conversion within the extruder, tin laurate catalyst was used at 90-degrees-C. In these conditions, an appropriate radical initiator can be introduced during the extrusion without double bond polymerization Comparing bulk and reactive extrusion prepared products, oligomer Tg were respectively -18-degrees-C and +8-degrees-C for oligomers and +18-degrees-C and +27-degrees-C for the issued networks.
