摘要: 1. POLYURETHANE ELASTOMERS PREPARED BY A PROCESS COMPRISING REACTING AN ARGANIC POLYISCYANATE WITH AN ORGANIC COMPOUND HAVING ACTIVE HYDROGEN ATOMS WHICH ARE REACTIVE WITH -NCO GROUPS AND A CHAIN-EXTENDING COMPOSITION COMPRISING A MIXTURE OF A COMPOUND OF THE FORMULA
HO-CH2-CH2-O-(1,4-PHENYLENE)-C(-R)2-(1,4-PHENYLENE)-O-CH2-
CH2-OH
WHEREIN R IS HYDROGEN OR METHYL; WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF C3 TO C7 ALKANE DIOLS OR A COMPOUND OF THE FORMULA
HO-CH2-CH2-NH-CO-(C(-R'')(-R"))X-(CO)Y-NH-CH2-CH2-OH
WHEREIN R'' AND R" ARE THE SAME OR DIFFERENT AND REPRESENTS HYDROGEN OR C1 TO C4 ALKYL; X IS 0 TO 4 AND Y IS 0 OR 1 WITH THE PROVISO THAT WHEN Y IS 0, X IS 0 AND WHEN Y IS 1, X IS O TO 4-

摘要: FLAME-RESISTANT POLYURETHANE POLYMERS ARE PREPARED BY REACTING A POLYISOCYANATE WITH AN ORGANIC COMPOUND HAVING ACTIVE HYDROGEN ATOMS WHICH ARE REACTIVE WITH -NCO GROUPS AND A CHAIN-EXTENDING COMPOSITION COMPRISING A MIXTURE OF 2,2-BIS(BROMOMETHYL)-1,3-PROPANEDIOL WITH A COMPOUND HAVING ONE OF THE FOLLOWING FORMULAS:
HO-(CH2)2-NH-CO-NH-(CH2)2-OH (I)
HO-(CH2)2-NH-CO-(CH2)N-CO-NH-(CH2)2-OH (II)
1,3-BIS(HO-CH2-CH2-)-BENZIMIDAZOLIDIN-2-ONE (III)
2-(HO-CH2-CH2-),5-(HO-CH2-CH2-NH-CO-)ISOINDOLENINE-
1,3-DIONE (IV)
WHEREIN N IS 0,1 OR 2.
