In order to improve these problems, it is known to incorporate polyfunctional acrylic acid esters such as ethylene glycol dimethacrylate, polyfunctional allyl alcohol esters such as diallyl phthalate, etc. into rubber as crosslinkable softeners. Although many of these known compounds have some effect in terms of softening effect and reactivity, they are liquid at room temperature, so they pose problems in handling, and they also have problems with the physical properties of the rubber after vulcanization, especially stress and stress under high temperatures. The heat resistance was not necessarily satisfactory.

In the present invention, the amount of the ester compound compounded in the rubber can be varied depending on the type of rubber and crosslinkable softener, the use of the vulcanized rubber compound, etc., but from the viewpoint of plasticizing effect and physical properties of the vulcanizate, it is usually 100% of the rubber. Based on the weight part, 1 to 30 parts by weight, preferably 2 to 20 parts by weight are selected.

In addition, as a method for polymerizing the ester compound in the present invention and co-crosslinking it with the rubber, simple sulfur vulcanization may be used, but peroxide vulcanization of rubber using a free radical catalyst, particularly an organic peroxide, is sufficient. It is more advantageous to carry out the polymerization and crosslinking reactions of the softener at the same time.

As described above, the present invention uses an ester compound obtained from a so-called oxystyrene compound, which is a phenol having a vinyl group in its side chain or its derivative, and a polyhydric carboxylic acid as a crosslinkable softener, and blends this into rubber. The main feature of the rubber composition thus obtained is that it has a higher viscosity after vulcanization than a rubber composition without a softener or a rubber composition containing a general softener such as current process oil. The tensile strength and stress become significantly large, and the extraction rate with solvents such as benzene becomes very small.
It exhibits excellent effects, with almost no phenomena such as oil migration or blooming observed on the surface of the vulcanizate.

Furthermore, since the ester compound used in the present invention is solid at room temperature and has at least two rigid aromatic nuclei, it is easier to process than when a known ester-based reactive softener is blended. It is easy to handle at times, and the physical properties of the rubber after vulcanization are significantly improved, such as heat resistance and stress at high temperatures.
