Method for making alkoxy-siloxane polyether carboxylates terminated with functional olefin groups

1. A resin comprising an alkoxy-siloxane polyester or polyether carboxylate backbone functionalized with at least two cycloolefin groups capable of undergoing a metathesis reaction, and having the formula:

wherein:

PE is a polyether or polyester fragment,

z=1-500,

q=0-10,

Q is a linear, branched, cyclic or polycyclic organic residue optionally containing siloxane groups (Si-O-Si) and optionally containing heteroatoms selected from the group consisting of B, N, O, Si, P, and S, and

D is a cycloolefinic residue and is different than Q.

2. The resin of claim 1 wherein D is a cycloolefinic residue selected from the group consisting of norbornenyl, norbornenylethyl, cyclopentenyl, 7-oxanorbornenyl, norbornadienyl, and 7-oxanorbornadienyl.

3. The resin of claim 1 wherein PE is a polyether containing propylene oxide (PO) and ethylene oxide (EO) fragments, z is about 16, q=0 or 1 and

4. The resin of claim 1 wherein PE is a polyether containing propylene oxide (PO) and ethylene oxide (EO) fragments, z=1-50, q=0-1 and

5. The resin of claim 1 further comprising a siloxane carboxylate backbone functionalized with at least two cycloolefin groups capable of undergoing a metathesis reaction, and being at least one of:

a pendant structure having the following formula:

a terminated structure having the following formula:

a cyclic structure having the following formula:

where m 1-50, n=0-200, p=0-200, x=3-6 and E is a cycloolefinic residue.

6. The resin of claim 5 wherein E is a cycloolefinic residue selected from the group consisting of norbornenyl, norbornenylethyl, cyclopentenyl, 7-oxanorbornenyl, norbornadienyl, and 7-oxanorbornadienyl.

7. The resin of claim 6 wherein D is a cycloolefinic residue selected from the group consisting of norbornenyl, norbornenylethyl, cyclopentenyl, 7-oxanorbornenyl, norbornadienyl, and 7-oxanorbornadienyl.

8. The resin of claim 7 wherein PE is a polyether containing propylene oxide (PO) and ethylene oxide (EO) fragments, z=1-50, q=0-1 and

9. A method of making a cycloolefinic functionalized alkoxy-siloxane polyester or polyether carboxylate, comprising reacting a hydride terminated siloxane with:

(a) a polyether or polyester diol containing propylene oxide and ethylene oxide fragments, and

(b) a cycloolefinic group functionalized hydroxyalkyl carboxylic acid ester, in the presence of a Group 3 or 13 catalyst.

10. The method of claim 9 wherein the catalyst is tris(pentafluoro-triphenyl)borane.
