Abstract
A composition prepared discontinuously by a polymerization reaction of a diisocyanate compound and a polyhydroxylated compound, followed by the termination reaction of the prepolymer of these compounds with a monoalcohol. This composition is mainly urethane polymers with strictly more than 3 residues of the polyhydroxylated compound. Further, the use of this polyurethane composition for bonding active electrode materials to a metal substrate.
Claims23
A non-aqueous composition C, comprising:
- a urethane polymer,
- wherein the non-aqueous composition C is discontinuously prepared by a process comprising:
- polymerizing, in the absence of any monohydroxyl compound, monomers comprising a diisocyanate compound (a) and polyhydroxylated compound (b), to obtain a prepolymer;
- followed by
- terminating the prepolymer with a terminator comprising a compound (c) of formula (I):
- wherein R is independently a straight C1-C40-alkyl group, a branched C3-C40-alkyl group, a C5-C40-cycloalkyl group, a straight C3-C40-alkylene group, a branched C3-C40-alkylene group, a C5-C40-aryl group, or a combination thereof,
- wherein urethane polymers comprising more than 3 residues of the compound (b) are a majority by number, measured by SEC.
