Claims
- 1. A method of producing a polyurethane including a desired moiety "M" comprising the steps of:
- selecting a compound having the formula A.sub.n --M, in which "M" represents the moiety desired for incorporation into the polyurethane, "A" represents a primary or secondary amine group and "n" is a number greater or equal to 2;
- reacting said selected compound with a cyclic carbonate to produce a urethane polyol; and
- reacting said urethane polyol with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 2. A method of producing a polyurethane including a desired moiety "M" comprising the steps of:
- selecting a compound having the formula A--M--A, in which "M" represents the moiety desired for incorporation into the polyurethane and in which "A" represents a primary or secondary amine group;
- reacting said selected compound with a cyclic carbonate to produce a urethane diol; and
- reacting said urethane diol with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 3. A method of incorporating a desired hydrocarbon moiety "R" into a polyurethane, comprising the steps of:
- selecting a compound having the general formula A.sub.n --R, wherein "A" represents a primary or secondary amine group, "R" represents the desired hydrocarbon moiety, and "n" is a number greater than or equal to 2;
- reacting said selected compound with a cyclic carbonate to produce a urethane polyol; and
- reacting said urethane polyol with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 4. A method of incorporating a desired hydrocarbon moiety "R" into a polyurethane, comprising the steps of:
- selecting a compound having the general formula A--R--A, wherein "A" represents a primary or secondary amine group and wherein "R" represents the desired hydrocarbon moiety;
- reacting said selected compound with a cyclic carbonate to produce a urethane diol; and
- reacting said urethane diol with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 5. A method of producing a segmented polyurethane which incorporates the hydrocarbon backbone of dimer acid, comprising the steps of:
- reacting dimer amine with a cyclic carbonate to produce a urethane diol; and
- reacting the urethane diol produced in the previous step with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 6. A method of producing a segmented polyurethane which includes a polyether backbone, comprising the steps of reacting an amino terminated polyether with a cyclic carbonate to produce a polyether urethane polyol; and
- reacting the urethane polyol produced in the previous step with one or more diisocyanates or polyisocyanates to produce a polyether urethane.
- 7. A method of producing a polyurethane which incorporates a polydimethylsiloxane backbone, comprising the steps of:
- reacting amino terminated polydimethylsiloxane with a cyclic carbonate to produce a urethane diol; and
- reacting the urethane diol produced in the previous step with one or more diisocyanates or polyisocyanates to produce a polyurethane.
- 8. A diol having the formula: ##STR7## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or alkyl groups and wherein D represents a dimer acid backbone.
- 9. A diol according to claim 8 wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen, methyl or ethyl groups.
- 10. A diol having the formula: ##STR8## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or alkyl groups.
- 11. A diol according to claim 10 wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen, methyl or ethyl groups.
- 12. A diol having the formula: ##STR9## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or alkyl groups.
- 13. A diol according to claim 12 wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen hydrogen, methyl or ethyl or ethyl groups.
