Abstract:
1. A hydroxyl-functional carbamoyl organosilicon compound which possesses: (i) at least one hydroxyl group bonded to a carbon atom and at least one carbamoyl group covalently bonded to a silicon atom through a silicon-carbon bond, and (ii) at least one divalent oxygen-containing group possessing at least two silyloxy bonds, wherein the hydroxyl-functional carbamoyl organosilicon compound is represented by the Formula (1): wherein: each occurrence of R each occurrence of R each occurrence of R each occurrence of X each occurrence of Z each occurrence of Z subscripts a, b, c, d, e, f, g and h are integers wherein a is 0 to 2; b is 0 to 3; c is 0 or 1; d is 1 to 4; e is 0 to 20, f is 1 to 4; g is 1 to 100; h is 2 to 3; i is 2 to 3 and j is 2 to 3, provided, when c is 1, a+b is 1; and when b is 0, then g is 1 and c is 1, wherein said hydroxyl-functional carbamoyl organosilicon compound is selected from the group consisting of [3-(2-ethoxy-5-methyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 2-hydroxy-ethyl ester; {3-[2-(3-hydroxy-2-methyl-propoxy)-5-methyl-[1,3,2]dioxasilinan-2-yl]-propyl}-carbamic acid 2-hydroxy-ethyl ester; [3-(2-ethoxy-5-methyl-[1,3]dioxan-2-yl)-propyl]-[3-(2-ethoxy-5-methyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 2-hydroxy-ethyl ester; [3-(2,4,4,6-tetramethyl-[1,3]dioxan-2-yl)-propyl]-[3-(2,4,4,6-tetramethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 2-hydroxy-ethyl ester; [3-(2,4,4,6-tetramethyl-[1,3]dioxan-2-yl)-propyl]-{[3-(2,4,4,6-tetramethyl-[1,3,2]dioxasilinan-2-yl)-propylamino]-methyl}-carbamic acid 2-hydroxy-ethyl ester; ({(2-hydroxy-ethoxycarbonyl)-[3-(2,4,4,6-tetramethyl-[1,3]dioxan-2-yl)-propyl]-amino}-methyl)-[3-(2,4,4,6-tetramethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 2-hydroxy-ethyl ester; ({(2,3-dihydroxy-propoxycarbonyl)-[3-(2,4,4,6-tetramethyl-[1,3]dioxan-2-yl)-propyl]-amino}-methyl)-[3-(2,4,4,6-tetramethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 2,3-dihydroxy-propyl ester; [3-(2,4-dimethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-{[[3-(2,4-dimethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-(2-hydroxy-1-methyl-ethoxycarbonyl)-amino]-methyl}-carbamic acid 3-hydroxy-1-methyl-propyl ester; [3-(2,4-dimethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-{[[3-(2,4-dimethyl-[1,3,2]dioxasilinan-2-yl)-propyl]-(2-hydroxy-1-methyl-ethoxycarbonyl)-amino]-methyl}-carbamic acid 3-hydroxy-1-methyl-propyl ester; [4-(2-ethoxy-4-methyl-[1,3,2]dioxasilinan-2-yl)-butyl]-[3-(2-ethoxy-4-methyl-[1,3,2]dioxasilinan-2-yl)-propyl]-carbamic acid 3-hydroxy-1-hydroxymethyl-propyl ester; {3-[2-(3-{2-[3-(2-hydroxy-ethoxycarbonylamino)-propyl]-[1,3,2]dioxasilinan-2-yloxy}-propoxy)-[1,3,2]dioxasilinan-2-yl]-propyl}-carbamic acid 3-hydroxy-propyl ester; {3-[bis-(3-{2-[3-(2-hydroxy-ethoxycarbonylamino)-propyl]-[1,3,2]dioxasilinan-2-yloxy}-propoxy)-3-hydroxypropoxy-silanyl]-propyl}-carbamic acid 3-hydroxy-propyl ester; {3-[{3-[[3-(2-hydroxy-ethoxycarbonylamino)-propyl]-(3-hydroxy-propoxy)-methyl-silanyloxy]-propoxy}-(3-hydroxy-propoxy)-methyl-silanyl]-propyl}-carbamic acid 2-hydroxy-ethyl ester; {[ethyl-{3-[ethyl-[(2-hydroxy-ethoxycarbonylamino)-methyl]-(3-hydroxy-propoxy)-silanyloxy]-propoxy}-(3-hydroxy-propoxy)-silanyl]-methyl}-carbamic acid 2-hydroxy-ethyl ester; {3-[(2-hydroxy-ethoxycarbonylamino)-methyl]-1,1,3,3-tetrahydroxy-disiloxanylmethyl}-carbamic acid 2-hydroxy-ethyl ester; and {3-[(2-hydroxy-ethoxycarbonylamino)-methyl]-1,1,3,3-tetramethyl-disiloxanylmethyl}-carbamic acid 2-hydroxy-ethyl ester.
