摘要： Novel amorphous copolyamides are provided which are the product of reaction of (A) a lactam, (B) a bisimidazoline, and (C) a dicarboxylic acid, wherein the proportions of reactants based on 100 mole percent are from about 43 to about 82 mole percent of lactam (A) and the remaining 18 to 57 mole percent divided between said (B) and said (C) in substantially equimolar proportions.The copolyamides are characterized by better resistance to elevated temperatures than 100 percent polycaprolactam polyamides but at the same time are easily molded because of their amorphous character.

摘要： A process for making glycerol di-tert-butyl ethers is disclosed. In one aspect of the invention, glycerol and isobutylene react in the presence of a β-zeolite having a silicon to aluminum ratio greater than 150. In another aspect, the etherification is performed in the presence of a β-zeolite and added tert-butyl alcohol. Each process selectively provides glycerol di-tert-butyl ethers while reducing the generation of isobutylene dimers and trimers. Utilizing both aspects of the inventive process simultaneously affords a diether product mixture containing less than 5 wt. % of isobutylene oligomers.

摘要： A gypsum composition containing a sulfonate-containing comb-branched copolymer is disclosed. The sulfonate-containing comb-branched copolymer comprises recurring units of a polyether macromonomer, an acrylic monomer, and a sulfonate monomer. The sulfonate-containing comb-branched copolymer not only increases the fluidity of gypsum slurry but also has reduced retardation on the gypsum setting.

摘要： Disclosed are new coatings compositions based on an HDI isocyanurate or biuret polyisocyanate and a bis(imine) reaction product of a diaminoalkane containing between two and five carbon atoms with an alkyl aldehyde containing between four and seven carbon atoms (advantageously a bis(imine) product of the reaction of 1,4-diaminobutane and isobutyraldehyde). The latter bis(imine) is completely miscible in HDI isocyanurate and biuret polyisocyanates, and, as a reactive diluent, allows the preparation of high performance coatings formulations that require only small amounts of solvents to achieve a conveniently sprayable viscosity.

摘要： Described are compounds characterized by the following formula: ##STR1## wherein C.sub.n H.sub.2n is alkylene from 2 to 12 carbon atoms and C.sub.m H.sub.2m is alkylene from 2 to 20 carbon atoms. Each of the alkylene groups can, optionally, be substituted by inert substituents. The compounds contain a free isocyanato group and a masked isocyanate group, namely, the cyclic urea moiety, which, when the compounds are heated, preferably in the presence of a catalyst, opens to give the group OCN--C.sub.n H.sub.2n --. Thus, the compounds can be reacted via the free isocyanate group with active hydrogen-containing monomers or polymers to form storage stable compositions which, upon heating, are curable via reaction with the cyclic urea group.

摘要： Bis(cyclic ureas) are disclosed which have the formula ##STR1## wherein R is ##STR2## and C.sub.n H.sub.2n is ethylene or 1,3-propylene each of which can be substituted by one or more inert substituents.These compounds are useful as masked diisocyanates which, on heating in the presence of a polyol and, optionally, a polyurethane catalyst, give rise to polyurethane resins. Accordingly, they are useful as a component of storage stable compositions which are convertible to polyurethanes upon heating. Such compositions are particularly useful as solvent-less coating compositions. The properties of the above compounds are distinguished in a number of respects from the known bis(cyclic ureas) in which C.sub.n H.sub.2n has 4 or more carbon atoms in the chain between the valencies. Illustratively, the above compounds are more stable on exposure to heat in the absence of catalysts but, in the presence of polyurethane catalysts, react with polyols at a significantly faster rate than the prior art compounds.
