Side chain fluorochemicals with crystallizable spacer groups |
| 摘要 |
A fluorochemical derived from monomers with a side chain, wherein the side chain includes a perfluoroalkyl group with 1-6 carbon atoms and a hydrocarbon spacer group attached to the perfluoroalkyl group, wherein the spacer group has 15-50 carbon atoms. The perfluoroalkyl group is non-crystallizable at room temperature and the spacer group is crystallizable at room temperature. |

1. A fluorochemical derived from a monomer composition comprising monomer comprising a side chain, wherein the side chain comprises:
a perfluoroalkyl group with 4 carbon atoms, wherein the perfluoroalkyl group is non-crystallizable at room temperature; and a linear hydrocarbon spacer group attached to the perfluoroalkyl group, wherein the spacer group has 17-22 carbon atoms, is a linear arrangement of methylene groups, and is crystallizable at room temperature; wherein said monomer comprising a side chain is selected from a group consisting of (meth)acrylates and urethane precursors and is the only fluorinated monomer present in said monomer composition. |
