Embodiment
Embodying the exemplary embodiments of feature of present invention and advantage will describe in detail in the following description.It should be understood that this
Invention can have various changes in different embodiments, and it is neither departed from the scope of the present invention, and description therein exists
Purposes of discussion is substantially treated as, and is not used to the limitation present invention.
An embodiment of the present invention provides a kind of sealant composition, including the polyisobutene that ethyl propionate is modified.Should
The polyisobutene that ethyl propionate is modified can be used as antioxidant, can not only improve the heat endurance and resistance to ag(e)ing of products made thereby
Can, while adhesive strength and peel strength of the product to backing can be also improved, serve cooperative effect.
In an embodiment of the present invention, the polyisobutene that ethyl propionate is modified can be made in the following way：Will be poly- different
Butylene oxidation is epoxidation polyisobutene, then epoxidation polyisobutene and ethyl propionate are reacted, and is made what ethyl propionate was modified
Polyisobutene.
The present invention is not limited the method for oxidation of polyisobutene, such as can be the polyisobutene in the presence of propionic acid
It is oxidized to epoxidation polyisobutene.Wherein, the mass ratio of polyisobutene and propionic acid can be (50~60):(15~30).
In an embodiment of the present invention, at 60~90 DEG C, such as 75 DEG C, polyisobutene be oxidized to epoxidation gather it is different
Butylene.
In an embodiment of the present invention, at 120~170 DEG C, such as 150 DEG C, epoxidation polyisobutene and propionic acid second
