SILYL TERMINATED SULFOPOLY(ESTER-URETHANE) PAVEMENT MARKING COMPOSITIONS

摘要

A pavement marking composition comprises a sulfopoly(ester-urethane) polymer which comprises in its backbone at least one non-terminal arylene or alkylene group comprising a pendant sulfonic acid group or salt thereof, the polymer of said pavement marking composition being terminated by at least one hydrolysable silyl group. A method of making the composition is disclosed. The pavement marking composition can further comprise at least one of pigments, optical elements, fillers, or other adjuvants. Particularly desirable adjuvants include optical elements, particularly retroreflective elements, skid-resistant particles, and pigments.
