A composition including at least one moisture-curable, semi-crystalline (meth)acrylic oligomer represented by the formula: wherein R 1 is independently a C 16 to C 40 alkyl group; R 2 is independently a C 16 to C 40 alkyl group; each R 3 is independently a methyl, ethyl, or isopropyl group; X is a chain transfer agent as defined further below; Y is independently selected to be a methyl, ethyl, or isopropyl group; a, b and c are each independently selected to be an integer of at least 10, and a+b+c≦1500; n≧1; and p is 0, 1, 2, or 3. The oligomer may be used advantageously as a coating, primer or adhesion promoter in construction articles, for example, adhesives, caulks, grouts, pavement markings, paving materials, ceramic tiles, or roofing granules. |
