Abstract

Solid, soluble products almost without crosslinking are manufactured by reaction of: (a) a polycaprolactone, MW 500-2000; and formula HOCH2(CH2)4COO- CH2(CH2)4COO n.CH2(CH2)4COOROH (n = 2-15 and R = 1-8C alkyl); (b) 2-6C a, omega -alkyleneglycol, (c) 4,4'-diphenylmethane diisocyanate or 4,4'-dicyclohexylmethane diisocyanate. Ratio NCO:OH reacted is approx. 1. Wt. ratio (%) is 80-98 pts (a) to 20-2 pts (b). Pref. reactants are 95 pts. polycaprolactone, MW 830 to 5 pts, 1,4-butanediol. Temp. of mixt. is raised to 100-150 degrees C for 1-4 hrs.
