C5 petroleum resin applied in road marking;

Hydrogenated C5 petroleum resin was prepared with C5 petroleum resins as feedstock at 240～270℃,14～17MPa,liquid space velocity 0.

The polymerization processes of C5 petroleum resin were reviewed,the applications of C5 petroleum resin in many fields such as adhesive,coating,paint,printing ink and color asphalt wered studied,and some advice was given to the petroleum resin factories.

This paper introduced and compared the processes of catalytic polymerization, thermal polymerization and initiative polymerization for producing C9 petroleum resin; summarized production status and products of C9 petroleum resin abroad; reviewed domestic C9 petroleum resin new processes and developing and modification of polymerization catalyst.

With C9 petroleum resin and bromine as materials, a bromizating C9 petroleum resin was synthesized.

This paper summarized the application of petroleum resin,modification of C9 petroleum resin,hope can increase the production capability and extend the production using scope,expect the researchful direction of the C9 petroleum resin,and outlook of application.

Used C_5 petroleum resin as the materials, through graft reaction, the polar groups was added onto the molecular of C_5 petroleum resin, prepared a new diesel oil pour point depression.

C_5 petroleum resin was modified with malefic anhydride as the modifier and DCP as the initiator.

The results showed that synthesis of C 9 petroleum resins using this liquid AlCl 3 as catalyst have good yield and light color.

A new EVA hot melt adhsive was prepared with maleic anhydide modified C 5 petroleum resin (MAH-C 5 ) as tackifier, and the influences were discussed including the kinds of EVA, the dosages of MAH-C 5 and paraffin.
