The craft of rosin modified Unsaturated Polyester Resins is confirmed, rosin modified Unsaturated Polyester Resins is made too, and measured or tested acid value, glue congeals time, thick layer solidification time, adhibit property and aspect of resins .The experimental result indicates that the acid value reduces along with the increasement of time. The glue congeals time increases along with the rising temperature. The time of solidification decreases along with the rising temperature. The craft of rosin modified Unsaturated Polyester Resins provides an accurate direction and experimental basis for the further research. The rosin modified Unsaturated Polyester Resins has favorable performances, which provides a wider applying prospect.
