TERMINALLY UNSATURATED POLYESTER WITH C-O-Si LINKAGE

A composition comprising an organosilyl-functional polyester, where the organosilyl-functional polyester is characterized by having multiple terminal carbon-carbon double bonds bound to the polyester through a carbon-oxygen-silicon linkage wherein the or organosilyl-functional polyester has an average chemical structure (I), (II), or (III):

• where:
• R is independently in each occurrence selected from hydrocarbyl groups having from one to 8 carbon atoms;
• X is independently in each occurrence selected from —H, —C(O)—(CH2)4C(O)OH and —C(O)—(CH2)4C(O)OSiR2—CH—CH2 where R is as described above provided at least two X group are —C(O)—(CH2)4C(O)OSiR2—CH═CH2 groups;
• subscript m independently in each occurrence has an average value in a range of one to 8,
• subscript n has an average value in a range of 2 to 50;
• and
• subscript o has an average value in a range of 2 to 10.
