High Temperature PA Alloy by Reactive Blending
关键字：Nylon alloy, Reactive blend, Non-viscoelastic, Heat resistance
Polyamide (PA) was blended with a reactive polyolefin, poly(ethylene-co-glycidyl methacrylate), at 70/30 wt. ratio using an extremely long (L/D=100, L: screw length, D:screw diameter) twin-screw extruder1).

Precise synthesis of sulfur-containing polymers via cooperative dual organocatalysts with high activity
关键字：Metal-free，carbonyl sulfide，100% alternating degree
Metal-free and controlled synthesis of sulfur-containing polymer is still a big challenge in
polymer chemistry. Here, we report a metal-free, living copolymerization of carbonyl sulfide
(COS) with epoxides via the cooperative catalysis of organic Lewis pairs including bases (e.g.:
phosphazene, amidine, and guanidine) and thioureas as hydrogen-bond donors, afford welldefined poly(monothi...
