Abstract
The present invention relates to a curable petroleum resin, a preparation method therefor, and use thereof, wherein the curable petroleum resin comprises a repeating unit derived from a petroleum resin monomer, a repeating unit derived from a silane monomer and a repeating unit derived from a cyclic anhydride monomer, and wherein the curable petroleum resin is used as an additive for a reactive polyolefin-based adhesive composition to increase the adhesive strength to a polyolefin-based substrate used for various parts.
Claims8
A curable petroleum resin comprising:
- a repeating unit (A) derived from a petroleum resin monomer;
- a repeating unit (B) derived from a silane monomer;
- and
- a repeating unit (C) derived from a cyclic anhydride monomer,
- wherein, based on the total weight of the repeating unit,
- the wt % of the repeating unit (A) derived from a petroleum resin monomer is 30% to 70%;
- the wt % of the repeating unit (B) derived from a silane monomer is 10% to 40%;
- and
- the wt % of the repeating unit (C) derived from a cyclic anhydride monomer is 10% to 30%,
- wherein the petroleum resin monomer comprises one selected from the group consisting of
- mixed C5 fractions and dicyclopentadiene,
- mixed C9 fractions and dicyclopentadiene, and
- mixed C5 fractions, mixed C9 fractions, and dicyclopentadiene,
- wherein the silane monomer is represented by the following Chemical Formula 2:
- CH2═CH(R1)—(COO)x(CnH2n)ySi(R2)(R3)(R4) [Chemical Formula 2]
- wherein R1 is hydrogen or a methyl group;
- R2 to R4 are the same as or different from each other, and hydrogen, or a C1 to C12 alkoxy group;
- n is an integer of 1 to 12 and
- x and y are 0 or 1.
