标题:Monolithic Nanoporous Polymers Bearing Poss Moiety As Efficient Flame Retardant And Thermal Insulation Materials
摘要:The Creation Of Porous Materials With Both Good Thermal Insulation And Flame Retardancy Is Of Great Importance For Construction Of Energy-Saving Coatings In Many Applications. Herein,We Report The Facile Fabrication Of octasilsesquioxane (Poss)-Based Monolithic Nanoporous Polymers (Named As Pdvb-Poss) By Solvothermal Method Using octavinyl-Poss As Monomer And Divinylbenzene (Dvb) As Crosslinker Followed By Freeze Drying. The As-Prepared Pdvb-Poss Show Abundant Porosity With Mesopore Sizes Ranging From 8 Nm To 13 Nm,Which Results In A High Thermal Insulation With A Low Thermal Conductivity Of 0.024 W M(-1) K(-1) In Air. The Pdvb-Poss Also Possesses Excellent Flame Retardancy With A Peak Heat Released Rate (Phrr) Of As Low As 144 W G(-1). Torch Burn Test Implies That The Pdvb-Poss Shows Self-Extinguishing Behaviors Without Generation Of Any Melt Dripping,Further Reflecting An Excellent Flame Retardancy. Taking Advantages Of Simple Fabrication Process,Easily To Be Scaled-Up,Excellent Thermal Insulation And Flame Retardancy,Such Poss-Based Monolithic Porous Polymers May Have Great Potential As Energy-Saving Coatings For Real Applications.

摘要:The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.
