[0071] Ethylene-methyl acrylate-vinyltrimethoxysilane terpolymer was prepared by free-to-initiated high-pressure polymerization in a high-pressure tubular reactor. The resulting elastomeric terpolymer contained 9 mole percent (31 percent by weight) methyl acrylate, 1 percent by weight vinyltrimethoxysilane, and had an MFR 2.16 The melting temperature is 10g / 10min, the melting temperature is 71°C, the crystallinity is 7% by weight, the Shore A hardness is 53, and the softness is 4.2MPa according to the dynamic shear modulus (according to ISO 6721-2A, 23°C). The amount is 2.4MPa.
[0072] The terpolymer was mixed with dodecylbenzenesulfonic acid (silane condensation catalyst) in a Brabender kneader at a temperature of 120° C. and a rotation speed of 40 rpm for 10 minutes. The composition was then molded into a 2 mm thick sheet and soaked in a water bath at a temperature of 60°C for 18 hours. The crosslinked sheet was removed from the water bath and the heat set value of the cr...
