If the oxypropylated glycerol used in example 1 is replaced with 30 parts of a solution of a polyesteramide-polyurethane condensation product prepared as described below, a product is obtained which requires spreading and which hardens within 30-60 minutes.

Oppløsningen av polyesteramid/polyuretan-kondenserings-produktet som anvendes i dette eksempel fremstilles ved følgende fremgangsmåte r The solution of the polyesteramide/polyurethane condensation product used in this example is prepared by the following method r

Et polyesteramid fremstilles ved å opphete en blanding A polyester amide is prepared by heating a mixture

av 4330 deler adipinsyre, 1820 deler etylenglykol, 177 deler dietylenglykol og 113 deler monoetanolamin ved 240°C, under tilbakeløp inntil det fåes et syretall av 2,0 til 3,0 mg KOH/g og produktet har en molekylvekt av 1850. of 4330 parts adipic acid, 1820 parts ethylene glycol, 177 parts diethylene glycol and 113 parts monoethanolamine at 240°C, under reflux until an acid number of 2.0 to 3.0 mg KOH/g is obtained and the product has a molecular weight of 1850.

En blanding av 1533 deler av det ovennevnte polyesteramid, 2108 deler metyletylketon, 2,08 deler vann, 10,75 deler etylenglykol, 0,77 deler dimetylaminopyridin og 188,5 deler av en 80r20-blanding av 2,4- og 2,6-tolylendiisocyanater omrøres ved 57 til 63°C inntil viskositeten av en prøve målt ved 25°C når en verdi mellom 100 og 140 poise. 13,5 deler metanol tilsettes derpå og blandingen omrøres ved samme temperatur i 3 timer. 0,38 deler salicylsyre tilsettes derpå og blandingen omrøres ved samme temperatur i 1 time og avkjøles derpå. Polyesteramid-polyuretanoppløs-ningen som man får på denne måte er da ferdig for bruk. A mixture of 1533 parts of the above polyesteramide, 2108 parts of methyl ethyl ketone, 2.08 parts of water, 10.75 parts of ethylene glycol, 0.77 parts of dimethylaminopyridine and 188.5 parts of an 80r20 mixture of 2.4- and 2.6 -tolylene diisocyanates are stirred at 57 to 63°C until the viscosity of a sample measured at 25°C reaches a value between 100 and 140 poise. 13.5 parts of methanol are then added and the mixture is stirred at the same temperature for 3 hours. 0.38 parts of salicylic acid are then added and the mixture is stirred at the same temperature for 1 hour and then cooled. The polyesteramide-polyurethane solution obtained in this way is then ready for use.

Mengden av vann som er angitt, er den totalt tilstedeværende, idet den faktiske mengde som tilsettes beregnes under hensyn-tagen til små mengder som er tilstede i oppløsningsmidlet. The amount of water indicated is the total amount present, as the actual amount added is calculated taking into account small amounts present in the solvent.
