Claims
- 1. In the process of sealing at least two glass plates to each other while maintaining a space therebetween, the improvement which comprises: applying to at least portions of at least one of said glass plates a sealant comprising at least one substantially saturated hydrocarbon polymer selected from the group consisting of isobutylene polymer and hydrogenated polybutadiene polymer, said substantially saturated hydrocarbon polymer having a molecular weight of 1000-15000 and having 1.1-5 silicon containing groups that have at least one hydroxyl or hydrolyzable group bonded to a silicon atom, said silicon containing group being present at terminals of the molecular chain of the substantially saturated hydrocarbon polymer; superposing said glass plates together such that said sealant contacts both plates; and curing said sealant.
- 2. A process of sealing glass plates as claimed in claim 1 wherein said silicon-containing group is represented by the formula (1): ##STR9## where each of R.sup.1 and R.sup.2 is independently a substituted or unsubstituted alkyl group having 1-20 carbon atoms, a substituted or unsubstituted aryl group having 6-20 carbon atoms, a substituted or unsubstituted aralkyl group having 7-20 carbon atoms, or a triorganosiloxy group represented by (R.sup.1).sub.3 SiO--, where R.sup.1 is a monovalent hydrocarbon group having 1-20 carbon atoms, provided that the three groups denoted by R.sup.1 may be the same or different, and when more than one R.sup.1 or R.sup.2 is present, they may be the same or different; X is a hydroxyl group or a hydrolyzable group, and when more than one X is present, they may be the same or different; a is 0, 1, 2, or 3; and b is 0, 1 or 2, provided that the sum of a and b is not less than 1; m is 0 or an integer of 1-19 and whem m is 2 or more, b in ##STR10## need not be the same.
- 3. A process of sealing glass plates as claimed in claim 2 wherein X in formula (1) is a hydrogen atom, a hydroxyl group, an alkoxy group, an acyloxy group, a ketoxymato group, an amino group, an amdio group, an aminooxy group, a mercapto group, or an alkenyloxy group.
- 4. A process of sealing glass plates as claimed in claim 2 wherein X in formula (1) is an alkoxy group.
