Abstract:
1. A silicon-containing polytrimethylene homo- or copolyether, wherein at least a portion of the polymer end groups are of the formula —O—Si(X)(Y)(Z), wherein X and Y, which may be the same or different, are groups that are easily displaceable from silicon by reaction with water and/or alcohols, wherein Z is selected from the group consisting of: (a) C 1 -C 20 linear or branched alkyl groups; (b) cycloaliphatic groups; (c) aromatic groups, each of (a), (b) and (c) being optionally substituted with a member selected from the group consisting of O, N, P and S; (d) hydrogen; and (e) groups that are easily displaceable from silicon by water and/or alcohol ;wherein the polytrimethylene homo- or copolyether has an Mw/Mn ratio of 1.7 or greater; and wherein from about 50 to 100 mole percent of the repeating units of the polytrimethylene homo- or copolyether are trimethylene ether units.
