Abstract
The present invention relates to curable polyurethane polymers made from renewable materials. In particular isosorbide derived from glucose is used. These renewable materials may be formed into curable polyurethane polymer compositions having different chemical functionalities and cure mechanisms.
Claims17
A (meth)acrylate functionalized isosorbide corresponding to the structure:
- MA-U-A-U-MA
- wherein A comprises an isosorbide unit, U comprises a urethane linkage and MA comprises a member selected from the group consisting of a (meth)acrylate-containing group, an acrylate-containing group and combinations thereof.
A method of forming a polyurethane polymer from a renewable source, said polyurethane polymer being (meth)acrylate functionalized, said method comprising:
- a) forming a polyurethane polymer by reacting isosorbide with a diisocyanate;
- b) reacting said polyurethane polymer with (i) a (meth)acrylate monomer containing hydroxyl functionality to yield said curable (meth)acrylate-funtionalized polyurethane polymer.
A polymerizable resin comprising:
- a) polymer corresponding to the structure:
- MA-U-A-U-MA
- wherein A comprises isosobide unit, U comprises a urethane linkage and MA comprises a (meth)acrylate-containing group;
- b) a cure system selected from the group consisting of a free radical initiator system.
A method for forming a polymerizable (meth)acrylate-functionalized polyurethane polymer comprising, reacting a (meth)acrylate-functionalized isocyanate compound with an isosorbide unit, said reacting being conducted for a time and at a temperature sufficient to form a polymerizable (meth)acrylate-functionalized polyurethane compound.
