Abstract
Un polímero de poli(óxido de alquileno) que contiene el residuo de un compuesto iniciador que contiene por lo menos un grupo halógeno o nitro, el polímero tiene un grado alcoxi promedio de polimerización de por lo menos tres moles de óxido de alquileno por equivalente del compuesto iniciador que es preparado por un proceso que comprende formar una mezcla de un compuesto iniciador halogenado o que contiene nitro que tiene uno o más grupos oxialkilatables, por lo menos un óxido de alquileno y un complejo catalizador de metal cianuro.A poly (alkylene oxide) polymer containing the residue of an initiator compound containing at least one halogen or nitro group, the polymer has an average alkoxy degree of polymerization of at least three moles of alkylene oxide per equivalent of initiator compound which is prepared by a process comprising forming a mixture of a halogenated or nitro-containing initiator compound having one or more oxyalkylatable groups, at least one alkylene oxide and a cyanide metal catalyst complex.
