A manufacturing method for a polyether polysiloxane block copolymer composition that can avoid the use and incorporation of aromatic hydrocarbon-based solvents is provided. The manufacturing method is generally easy on an industrial production scale. The manufacturing method includes a step of obtaining a polyether polysiloxane block copolymer (A) by a specific reaction in the presence of a saturated hydrocarbon solvent (C) having an average number of carbon atoms in a range of 6 to 11, and a step of replacing the solvent (C) used in the reaction with (B) a (poly)glycol or a polyglycol derivative diluent, either during or after the aforementioned step. Also provided is a method of manufacturing a foam stabilizer or the like using the composition obtained by the aforementioned manufacturing method.

A polyisocyanurate raw material composition containing a polyfunctional isocyanate, a compound (I) represented by general formula (I) shown below, and an epoxy compound. In general formula (I), each of R.sup.1 to R.sup.5 represents a hydrogen atom, an alkoxy group of 1 to 10 carbon atoms, an alkyl group of 2 to 10 carbon atoms (or an alkyl group of 1 to 10 carbon atoms in the case of R.sup.3 to R.sup.5), an aryl group of 6 to 12 carbon atoms, an amino group, a monoalkylamino group of 1 to 10 carbon atoms, a dialkylamino group of 2 to 20 carbon atoms, a carboxy group, a cyano group, a fluoroalkyl group of 1 to 10 carbon atoms, or a halogen atom (provide that R.sup.1 and R.sup.2 are not both hydrogen atoms). ##STR00001##

Flexible polyurethane foams are made by reacting a hydrophilic quasi-prepolymer, water and a polymer polyol in the presence of a silicone surfactant and an ethylene oxide/higher alkylene oxide block copolymer. The foams exhibit desirably low densities and compression sets, and have good thermal and moisture-wicking properties. The foams are useful in bedding and other comfort applications in which they are exposed to body heat and bear at least a portion of the weight of the user. The thermal and moisture wicking properties contribute to perceived comfort for the user.

Disclosed herein is a coating material system containing (A) at least one polyhydroxy group-containing compound, (B) at least one polyisocyanate-containing compound, and (C) at least one catalyst comprising lithium (Li) and bismuth (Bi) as metal components and where the molar ratio of lithium to bismuth is at least 7:1 [mol/mol], in which i) components (A), (B), and (C) are present separately from one another, or ii) are mixed wholly or at least partly with one another. Methods for producing and using the coating material system are also disclosed herein.
