摘要： A process is claimed for the prodn. of moulded prods. (I) consisting of a preformed film made of flexible plastic (II), backed with a layer of polyurethane foam (III); the novelty is that any faults in the film produced during mfr. or further processing are repaired before the foaming process by treatment with an aq. dispersion of film-forming polyurethane (IV). Specifically (IV) is derived from (a) 1 mol. (NCO) di- or poly-isocyanate, (b) 0.1-0.8 mol. (OH) di- or poly-hydric alcohol with mol. wt. 400-6000, (c) 0.05-0.5 mol. (OH and/or NHR) of a cpd. contg. OH and/or NHR gps. together with ionic gp(s)., (d) 0-0.5 mol. (OH) di- or polyhydric alcohol with mol. wt. 62-400, (e) 0-0.4 mol. (NHR) di- or poly-amine with prim. or sec. amino gps. (with R = H, 2-4C alkyl or a moiety contg. the gp. NHR), (f) 0-0.4 mol. (OH + NHR) aminoalcohol with prim. and/or sec. amino gp(s). and (g) 0-0.2 mol. (OH) monohydric polyether-alcohol, such that total OH and/or NHR gps in components (b)-(g) = 0.9-1.2 mol.; (b) is a poly-THF, present as an alpha, omega-diol, and (c) is 2,2-bis-(hydroxymethyl)-propionic acid. USE/ADVANTAGE - The process is useful, e.g. in the prodn. of seats, arm rests, instruments panels, interior linings, etc. for motor vehicles and aircraft; the process makes it possible to use substrate film (II) which has been damaged (e.g. during deep-drawing, processing by the powder-slush method, etc.), by repairing the damage as above.

(Monomer II), (c) dihydric alcohol(s) with Mn 400-6000 or a mixt. of alcohols with similar Mn and mean OH functionality 1.5-2.5 (Monomer III), (d) dihydric alcohol(s) with Mn 62-399 or a mixt. of alcohols with similar Mn and mean OH functionality 1.5-2.5 (Monomer IV), (e) cpd(s). with ionisable gp(s). and at least one alcoholic OH or -NH- gp. (Monomer V), (f) 0, 1 or more polyamines with at least 2 -NH- gps. (Monomer VI), (g) 0, 1 or more cpd(s). with alcoholic OH gp(s). and -NH- gp(s). (Monomer VII) and (h) 0, 1 or more monohydric polyether-alcohols (Monomer VIII); the amts. of monomers are such that the equiv. ratio (OH + -NH-)/NCO is 0.1-0.4 for (III)/(I + II), 0.5-0.8 for (IV)/(I + II), 0.05-0.5 for (V)/(I + II), 0-0.4 for (VI)/(I + II), 0-0.4 for (VII)/(I + II), 0-0.2 for (VIII)/(I + II) and 0.80-1.25 for (total III-VIII)/(I + II); (I + II) contains 50-90 mol.% (I), and 0.05-2 mmols. of the ionisable gps. in monomer (V) are ionised per g PU in the prepn. Also claimed is a process for the prodn. of the above PU prepns. USE/ADVANTAGE - Prepns. are useful as binders for coating materials for various substrates, esp. leather (claimed). The prepns. give a final coating with a reduced level of gloss, combined with high abrasion resistance, high water resistance and elasticity. (7pp Dwg.No.0/0)

Independent claims are also included for: (a) a process for the production of these solid carbodiimides from di-isocyanates in which the isocyanate (NCO) groups are not attached to aromatic carbon, by reaction in presence of catalysts to form the carbodiimide with cleavage of carbon dioxide, followed by reaction with compounds containing at least two NCO-reactive groups; (b) another process in which the above stages are reversed and the ratio of NCO groups to NCO-reactive groups used in the first stage is at least 2:1; (c) solid carbodiimides obtained by these processes; (d) mixtures containing compounds with ester units together with these carbodiimides; and (e) mixtures containing these carbodiimides and at least one of the following: polyurethanes with ester units and/or polycondensation products such as polyesters, e.g. polyethylene- or polybutylene- terephthalate, polyether-esters, polyester-esters, polyester-amides, polycaprolactones, unsaturated polyester resins and polyamides.
