摘要： Composite polymers, especially composite polyols containing active hydrogen atoms can be prepared by polymerizing one or more olefinically unsaturated compounds in the presence of a liquid polymer containing active hydrogen atoms and a modified initiator; the modification comprising the reaction between a liquid polymer containing one or more groups which can react with isocyanato groups and a compound containing two or more isocyanato groups which has been partially converted by reacting it with an organic hydroperoxide or a free-radical initiator also containing additional active hydrogen atoms. The composite polymers exhibit a stable dispersed polymer phase and can be suitably applied as starting materials for polyurethane foams.

摘要： Normally sparingly soluble magnesium alkoxide is solubilized in alkanol by the additional presence of certain acidic materials. The resulting solution is used to produce a mixture of substantially spherical particles, substantially free of fines, containing an adduct magnesium alkoxide. The particles are converted by conventional methods to a procatalyst precursor of an olefin polymerization catalyst of good activity and good selectivity to stereoregular polymer whenever appropriate, which catalyst produces polymer product of good morphology.
