Abstract
Low unsaturation, high molecular weight polyols having an unsaturation level below or equal to 0.006 milli-equivalents per gram, and preferably below 0.004 milli-equivalents per gram, and molecular weights of greater than or equal to about 2,000, and preferably between about 2,000 and 10,000, are converted into low unsaturation, high molecular-weight (LUSHMW) polyamines directly by amination reactions. The LUSHMW polyamines produce polymers having elongation, modulus, and tensile characteristics that are substantially better than those of conventional analogous polymers.
Claims43
A polymer comprised of a reaction product of
- a polyamine having an end-group unsaturation of less than 0.006 milli-equivalents/gram and a molecular weight greater than 2,000, and
- a di- or higher functional electrophilic monomer.
A method for preparing a polymer having superior properties, comprising:
- converting a polyol having a molecular weight greater than or equal to 2000 and an end-group unsaturation level of less than or equal to 0.006 milli-equivalents per gram into a high molecular weight low unsaturation polyamine;
- and
- reacting the high molecular weight low unsaturation polyamine with a di- or higher functional electrophilic monomer to produce a low unsaturation high molecular weight amine-functionalized (LUSHMW-AF) polymer.
A polymer comprising:
- a reaction product of a polyamine, the polyamine comprising a reaction product of:
- a polyol having an unsaturation of less than 0.006 milli-equivalents/gram, the polyamine having a primary amine functionality of greater than 1.98;
- and
- an electrophilic monomer.
