Claims
- 1. A composition comprising:
(A) non-branched polybutadiene having terminal hydroxyl functionality less than 2 per molecule by average; and (B) branched polybutadiene having terminal hydroxyl functionality more than 2 per molecule by average; the weight ratio of (A) to (B) being about 99:1 to 1:99.
- 2. The composition of claim 1 wherein the ratio of (A) to (B) is about 10:90 to 90:10.
- 3. The composition of claim 1, wherein the non-branched polybutadiene (A) has terminal hydroxyl functionality of about 1.8-1.9 and the branched polybutadiene (B) has terminal functionality of about 2.4 to 2.6.
- 4. The reaction product of the composition of claim 1 with a monomer or polymer (C), the reaction product having one or more hydroxyl, isocyanate, carboxyl, phenol, epoxy, or amine terminal groups.
- 5. A curable composition comprising the reaction product of claim 4 and one or more chain extending agents.
- 6. The composition of claim 1 further comprising a polyfunctional monomer or polymer (C) having functionality which is reactive with the terminal hydroxyl groups of (A) and (B).
- 7. The composition of claim 6 wherein the polyfunctional monomer or polymer (C) is selected from organic polyisocyanates, polyamides, polyamines, anhydrides of dicarboxylic acids, polyepoxides, and polyesters.
- 8. A prepolymer which is the reaction product of the composition of claim 1 with an organic polyisocyanate (C).
- 9. The prepolymer of claim 8 wherein the organic polyisocyanate (C) is selected from the group consisting of 4,4′-methylenebis(phenyl isocyanate), toluene diisocyanate, and hexane diisocyanate.
- 10. A curable composition comprising the prepolymer of claim 8 and a chain extending monomer.
- 11. The curable composition of claim 10 wherein the chain extending monomer is selected from the group consisting of diol and diamine.
- 12. A direct cured polyurethane composition comprising prepared by reacting the composition of claim 1 with a polyisocyanate.
- 13. Composition of claim 12 in a form selected from roof water-resistant membrane, insulated glass sealant, hot melt adhesive, geo-membrane, and liquid binder in brake system.
- 14. Method of preparing compositions of claim 1 comprising blending (A) and (B) in a ratio of 99:1 to 1:99 by weight.
- 15. Method of preparing prepolymers comprising reacting a composition according to claim 1 with organic polyisocyanate, phenol, amine, dianhydride, or peracid.
- 16. Method of preparing cured thermoplastic resins comprising reacting a prepolymer prepared according to claim 15 with a polyfunctional monomer.
- 17. Method of preparing a roof water-resistant membrane, insulated glass sealant, hot melt adhesive, geo-membrane, or liquid binder for a brake system comprising reacting a prepolymer prepared according to claim 15 with a polyfunctional crosslinking monomer.
