Abstract
The present invention relates to functionalized cyclic carbonates, urethanes and polyurethanes, their methods of production and uses thereof.
Claims31
A method of producing a functionalized cyclic carbonate comprising the steps of:
- a) providing a polyol having at least one functional group chosen from the group of hydroxyl, alkylhydroxyl, allyl, allylether, acryl, and methacryl;
- b) admixing a dialkyl carbonate or a biphenyl carbonate and said functionalizes polyol of a) forming a mixture;
- c) heating the mixture of b) to obtain a cyclic functionalized carbonate.
The method of producing a polyurethane comprising the steps of:
- m) providing a bicyclic carbonate having the formula
- wherein R is chosen from a bond, oxygen, alkyl having 1-10 carbons, ketone, and ester;
- R1 and R2 may independently be chosen from H, alkyl, hydroxyl, hydroxyalkyl, alkylcarbonyl, carbonylalkyl, alkoxycarbonyl, alkoxycarbonyloxy and carboxyl group;
- and R3 is chosen from alkyl having 1-20 carbons, cycloalkyl, alkylphenyl, isophorone, polyamines, and derivatives thereof;
- n) providing a diamine;
- o) forming a mixture of said bicyclic carbonate of m) and said diamine of n);
- p) allowing reaction of the mixture of o);
- q) obtaining a polyurethane having the formula
- wherein R is chosen from a bond, oxygen, alkyl having 1-10 carbons, ketone, ester,
- R1, R2 independently are chosen from H, alkyl, hydroxyl, hydroxyalkyl, alkylcarbonyl, carbonylalkyl, alkoxycarbonyl, alkoxycarbonyloxy and carboxyl group,
- R3 is chosen from alkyl having 1-20 carbons, cycloalkyl, alkylphenyl, isophorone, polyamines and derivatives thereof.
