<p>#CMT# #/CMT# Composition comprises 0.1-20 mass.% of an additive mixture containing at least one organic phosphorus compound (A) and at least one compound (X), which has at least two functional groups capable of reacting with isocyanate groups (isocyanate-reactive groups) and has an equivalent mass of less than 400 g/mole. #CMT# : #/CMT# Composition comprises 0.1-20 mass.% of an additive mixture consists of at least one organic phosphorus compound (A) of formula (I), (H-O-(CH(R5a)-CH(R5)-O) r-[p(=O)(R)-(O-CH(R4)-CH(R4a)) s-O] t-H) (II) or (H-O-(CH(R5a)-CH(R5)-O) r-[p(=O)(R6)-(O-CH(R4)-CH(R4a)) s-O] t-H) (III) and at least one compound (X), which has at least two functional groups capable of reacting with isocyanate groups (isocyanate-reactive groups) and has an equivalent mass of less than 400 g/mole, or of (III). R1-R5, R1a-R5a : H, alkyl or phenyl; R : H, alkyl, phenyl, H-O-(CH(R5a)-CH(R5)-O) r- or -[p(=O)(R)-(O-CH(R4)-CH(R4a)) s-O] t-H; R6 : -(CH 2) o-OH; m, n, p, q, r, t : >= 1, where r+s = 4-60; s : 0 or >= 1; and o : 1-5. Independent claims are included for: (1) a polyurethane system, obtained by processing the composition; (2) a polyurethane foam, obtained by processing the composition; (3) a laminated structure comprising the polyurethane system or the composition that is hot adhesively bonded to a substrate; and (4) producing the laminated structure, comprising hot adhesive bonding of the polyurethane system or the composition with a substrate. #CMT#[Image]#/CMT# #CMT#USE : #/CMT# The composition is useful for producing: polyurethane systems that are used for hot adhesive bonding; laminated structures; producing the polyurethane system; and polyurethane foam (all claimed). #CMT#ADVANTAGE : #/CMT# The composition: exhibits improved initial adhesion and improved hydrolysis stability, and is free of halo-additive, which displays reduced smoking during hot adhesive bonding. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Composition: The composition further comprises: at least one isocyanate component and at least one polyol component; and one of more blowing agents, one or more urethane catalysts, and/or one or more isocyanurate catalysts. Preferred Components: The additive mixture is a mixture of (X) and (A). (X) contains ethylene oxide units. (X) comprises glycerol polyether and/or ethoxylated bisphenol A. The glycerol polyether contains 9-12 alkylene oxide units, and the ethoxylated bisphenol A contains 5-7 ethylene oxide units. The amount of (A) and (X) is 1-25 parts by mass and 75-99 parts by mass, respectively. #CMT#EXAMPLE : #/CMT# No suitable example given.</p> |
