    摘要： Novel ester diol alkoxylates produced by the reaction of an ester diol and an alkylene oxide. The reaction product is a vehicle useful in ink or paint formulations, as a solvent, and in adhesive formulations; it is also useful as an intermediate in the production of other valuable compounds and as a surfactant.

    摘要： Polymers which comprise polymer chains along which the proportion of mer units provided by a first heterocyclic monomer gradually increases in a given chain length as the proportion of mer units provided by a second heterocyclic monomer gradually decreases along said chain length. In one form, the portions of the polymers adjacent one end of the given chain lengths have about 100% of mer units provided by the first monomer and about 0% of mer units provided by the second monomer and the portions adjacent the other end of the given chain lengths have about 0% of mer units provided by the first monomer and about 100% of mer units provided by the second monomer. Additional forms of polymers are disclosed.Process for producing such polymers comprising introducing at least one primarily polymerizable feed composition comprising at least one of the monomers described above from at least one primary feed source to a polymerization zone, the primary polymerizable feed composition continually varying in compositional content of the monomers therein during said continuous introduction; simultaneously adding to primary feed source at least one different secondary polymerizable feed composition comprising at least one different monomer as described above from at least one secondary feed source so as to continually change the compositional content of the polymerizable monomers in the primary polymerizable feed composition in the primary feed source; and continuously polymerizing the primary polymerizable feed composition introduced to the polymerization zone until desired polymerization has been achieved.The method of this invention is particularly useful in controlling the ratio of primary to secondary hydroxyl terminal groups in the product.

    摘要： This invention relates to heterogeneous (organic polymer-supported) calcium-containing catalysts and the use thereof in the preparation of alkoxylation products, i.e., condensation reaction products of alkylene oxides and organic compounds having at least one active hydrogen. In another aspect of this invention, processes are provided for preparing heterogeneous (organic polymer-supported) calcium-containing catalysts for alkoxylation using calcium oxide or calcium hydroxide as sources for the catalytically-active calcium. In a further aspect of this invention, alkoxylation products are provided that have beneficial, narrow molecular weight ranges and are essentially neutral in pH and free from catalyst residues.

    摘要： Acrylyl esters of polyester-polyether copolymers are produced by reacting a hydroxyl-terminated polylactone polyester with alkylene oxide and esterifying the resulting polyester-polyether copolymer with an unsaturated carboxylic acid such as acrylic acid or methacrylic acid. The resulting reactive esters are useful in ink, coating or adhesive formulations curable by thermal or radiation means.
