摘要:The present application discloses an implantable material and a synthesis method therefor and a prosthetic heart valve. The implantable material uses polyurethane, the molecular chain structure of polyurethane comprises a soft segment and a hard segment, and a functional branched chain is grafted onto the hard segment; the solubility parameter of the functional branched chain is 6-8. According to the present application, by introducing the functional branched chain into the hard segment, the compatibility between the hard segment and the soft segment is improved and the stress transfer points between the hard segment and the soft segment are increased, so that the prepared implantable polymer material has excellent mechanical properties.

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.

摘要:Hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof are prepared by reacting a difunctional or polyfunctional monomer having functional groups of one type (A) without any other functional groups capable of reacting significantly during polymerization, and a difunctional or polyfunctional monomer having functional groups of another type (B) without any other functional groups capable of reacting significantly during polymerization, wherein each A-functional group is reacted with a B-functional group, and wherein at least one of the monomers has a functionality of at least three. The process enables hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof to be prepared at a lower cost than with conventional synthesis processes, and provides greater flexibility in the preparation of a larger variety of different types of hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof.

摘要:The present invention discloses a phosphorus-silicon synergistic flame retardant and the preparation method and use thereof. The phosphorus-silicon synergistic flame retardant provided by the present invention has a structural general formula shown as formula I. A new type of compound containing phosphorus and silicon is prepared by the present invention using the cheap organic boron catalyst, and employing the addition reaction of diphenyl phosphine oxide and derivatives thereof with silicone containing carbon-carbon double bond. Such compounds have the properties of hydrolytic resistance, easy purification, and low synthesis cost, etc. Phosphorus and silicon elements in the molecular structures of such compounds both can act as the flame retardants solely, and meantime can work synergistically, thereby enduing the common polymeric materials with the excellent flame retardant property.
