Abstract

The present invention relates to a liquid composition comprising at least one silylated polymer and at least one tin-free polyhedral oligomeric titanium silsesquioxane in liquid form.

First claim

1 . A liquid composition comprising at least one silylated polymer and at least one tin-free polyhedral oligomeric titanium silsesquioxane in liquid form, which is a compound of formula (I):

wherein,
Z is —OH or —O—C 1-10 alkyl, preferably —O—C 1-4 alkyl, more preferably —O-methyl or —O— ethyl;
wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 are independently selected from substituted or unsubstituted C 8-20 alkyl, substituted or unsubstituted C 8-20 cycloalkyl, substituted or unsubstituted C 8-20 alkenyl, or substituted or unsubstituted C 8-20 aryl;
Or
wherein R 1 to R 7 are each substituted or unsubstituted C 8 alkyl or C 9 alkyl or C 10 alkyl or C 11 alkyl or C 12 alkyl or C 13 alkyl or C 14 alkyl or C 15 alkyl or C 16 alkyl or C 17 alkyl or C 18 alkyl or C 19 alkyl or C 20 alkyl or combinations thereof;
Or
wherein at least one first radical of R 1 to R 7 is chosen from substituted or unsubstituted C 8-20 alkyl, substituted or unsubstituted C 8-20 cycloalkyl, substituted or unsubstituted C 8-20 alkenyl, or substituted or unsubstituted C 8-20 aryl, and wherein at least one second radical of R 1 to R 7 , different from said at least one first radical, is selected from substituted or unsubstituted C 1-7 alkyl, substituted or unsubstituted C 1-7 cycloalkyl, substituted or unsubstituted C 1-7 alkenyl, or substituted or unsubstituted C 1-7 aryl, and wherein the remaining radicals of R 1 to R 7 are independently selected from substituted or unsubstituted C 1-7 alkyl, substituted or unsubstituted C 1-7 cycloalkyl, substituted or unsubstituted C 1-7 alkenyl, or substituted or unsubstituted C 1-7 aryl, substituted or unsubstituted C 8-20 alkyl, substituted or unsubstituted C 8-20 cycloalkyl, substituted or unsubstituted C 8-20 alkenyl, or substituted or unsubstituted C 8-29 Aryl.

2 . The composition according to claim 1 , wherein at least 2 radicals from R 1 to R 7 are selected from substituted or unsubstituted C 8-20 alkyl, substituted or unsubstituted C 8-20 cycloalkyl, substituted or unsubstituted C 8-20 alkenyl, or substituted or unsubstituted C 8-20 aryl, and wherein the remaining ones are independently selected from substituted or unsubstituted C 1-7 alkyl, substituted or unsubstituted C 1-7 cycloalkyl, substituted or unsubstituted C 1-7 alkenyl, or substituted or unsubstituted C 1-7 aryl.

3 . The composition according to claim 1 , wherein at least 2 radicals from R 1 to R 7 are each substituted or unsubstituted C 8 alkyl or C 9 alkyl or C 10 alkyl or Cu alkyl or C 12 alkyl or C 13 alkyl or C 14 alkyl or C 15 alkyl or C 16 alkyl or C 17 alkyl or C 18 alkyl or C 19 alkyl or C 20 alkyl, and wherein the remaining ones are independently selected from substituted or unsubstituted C 1-7 alkyl, substituted or unsubstituted C 1-7 cycloalkyl, substituted or unsubstituted C 1-7 alkenyl, or substituted or unsubstituted C 1-7 aryl.

4 . The composition according to claim 1 , wherein at least 20% in mole of R 1 to R 7 are individually selected from the list consisting of substituted or unsubstituted C 8-20 alkyl, preferably C 8-18 alkyl C 8-20 cycloalkyl, substituted or unsubstituted C 8-20 alkenyl, or substituted or unsubstituted C 8-20 aryl, when Z is OH or O—C 1-4 alkyl.

5 . The composition according to claim 1 , wherein said silylated polymer comprises a silane moiety with at least one radical, when Z is respectively, O-methyl or O-ethyl.

6 . The composition according to claim 1 , wherein said at least one tin-free polyhedral oligomeric titanium silsesquioxane is in liquid form, in the absence of solvent.

7 . The composition according to claim 1 , wherein silylated polymer is selected from the group consisting of silylated polyether, silylated silicone and silylated polyurethanes.

8 . The composition according to claim 7 , wherein said silylated polymer comprises alkoxysilyl or silanol moieties.

9 . The composition according to claim 7 , wherein said silylated polymer is obtained by reaction of at least one isocyanate with at least one isocyanate reactive compound and with at least one alkoxysilane compound.

10 . The composition according to claim 1 , wherein the amount of said tin-free polyhedral oligomeric titanium silsesquioxane is ranging from 0.001 wt % to 5 wt % based on total weight of the composition.

11 . The composition according to claim 1 , wherein said composition contains less than 0.001 wt % of tin.

12 . A moisture curable silylated polymer composition obtainable by applying the following steps:
providing at least one silylated polymer as defined according to any one claim 1 ; and mixing said at least one silylated polymer with at least one tin-free polyhedral oligomeric titanium silsesquioxane in liquid form as defined according to claim 1 .

13 . A process for manufacturing a moisture curable silylated polymer composition, which process comprises the following steps:
adding said at least one silylated polymer composition to at least one tin-free polyhedral oligomeric titanium silsesquioxane in liquid form as defined according to claim 1 ; and curing said silylated polymer composition.
