Lipatova, T. E. published the artcileRole of complex formation in catalysis of polyaddition reactions with isocyanates, Computed Properties of 14284-06-1, the publication is Polymeric Materials Science and Engineering (1983), 346-9, database is CAplus.
The catalytic activity of copper bis(Et acetoacetate) (I) [14284-06-1] in the polymerization of 4,4‘-diphenylmethane diisocyanate [101-68-8] with poly(ethylene glycol) (II) [25322-68-3] decreases with the growth in II mol. mass due to the reduced concentration of OH-OH-type associates and the increased contribution of O atoms of the glycol ether groups into complex formation with I. The activating influence of I depends on the stability of its complex with glycol. The activity of amine-epoxide catalysts in isocyanate cyclotrimerization was also discussed.
Polymeric Materials Science and Engineering published new progress about 14284-06-1. 14284-06-1 belongs to copper-catalyst, auxiliary class Copper, name is Copper(II) ethylacetoacetate, and the molecular formula is 0, Computed Properties of 14284-06-1.
