METHOD FOR PRODUCING HIGH MOLECULAR WEIGHT POLYOXYALKYLENE POLYOLS
The invention relates to an efficient method for producing polyoxyalkylene polyols with equivalent molar masses between 9500 and 23000 g/mol from one or more H-functional starter compounds, and one or more alkylene oxides in the presence of a double metal cyanide catalyst, characterised in that the alkylene oxide metering rate is reduced once a calculated equivalent molar mass of between 8000 and 9500 g/mol is reached.

Polyether-modified polybutadienes and processes for preparation thereof
A process can be used for preparing polyether-modified polybutadienes. The process involves reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C). The at least one epoxy-functional polybutadiene (C) is then reacted with at least one hydroxy-functional compound (D) to give at least one hydroxy-functional polybutadiene (E). The at least one hydroxy-functional polybutadiene (E) is finally reacted with at least one epoxy-functional compound (F) to give at least one polyether-modified polybutadiene (G).
Alkoxysilyl-containing adhesive sealants with intrinsically reduced viscosity
The present invention provides specific alkoxylation products, a process for preparing them, compositions comprising these alkoxylation products, and their use.
Polymer having terminal structure including plurality of reactive silicon groups, method for manufacturing same, and use for same
A polymer (A) having, at one terminal moiety thereof, a terminal structure having two or more carbon-carbon unsaturated bonds. A reactive-silicon-group-containing polymer (B) having, at one terminal moiety thereof, a terminal structure having two or more reactive silicon groups.
Amphiphilic Graft Copolymers
A novel amphiphilic graft copolymer is described. A process to make amphiphilic graft copolymers via grafting either poly(ethylene oxide) or polylactide side chains onto an EVA platform using oxo-anion ring-opening polymerization chemistry is also described. Polyethylene or polypropylene based graft copolymers are prepared starting from poly(ethylene-co-vinyl acetate) or maleic anhydride grafted isotactic polypropylene respectively. The amphiphilic character will result from the incorporation of hydrophilic poly(ethylene oxide) (PEO) side-chains. Various applications of the novel amphiphilic graft copolymer are also described including, but not limited to, thermoplastic elastomer, films, fibers, fabrics, gels, breathable packaging materials, additive for biodegradable system, surfactant, antistatic additives, polymer compatibilizers, phase transfer catalysts, solid polymer electrolytes, biocompatible polymers, or incorporation into the materials listed above.
