Definitions
- the present invention relates to compositions comprising an elastomer susceptible to oxi- dative, thermal, dynamic, or light- and/or ozone-induced degradation, a white reinforcing filler, and as coupling agent at least a thio substituted siiane or an oligomeric hydrolysis product thereof; to new coupling agents; and to a process for ensuring the coupling of a white reinforcing filler to elastomer compositions reinforced by a white filler, which comprises incorporating into the elastomer at least a thio substituted siiane or an oligomeric hydrolysis product thereof and vulcanizing the composition.
- TESPT bis-triethoxysilylpropyl-tetrasulfane
- U.S. 6,313,205 disclosed a sulfur-vulcanizable rubber composition comprising at least one diene elastomer, a white reinforcing filler, and a coupling agent selected from the group of polyorganosiloxanes.
- U.S.-A-2003/0199619 discloses blocked mercaptosilane condensates as coupling agents in mineral filled elastomer compositions.
- Among the advantages in the use of these blocked mercaptosilane condensates over the use of previously described blocked mercaptosilanes are the release of less volative organic compounds during the elastomer compounding process and lower coupling agent loading requirements.
- the known coupling agents for mineral filled elastomers do not satisfy in every respect the high requirements which a coupling agent is required to meet, especially with regard to the final mechanical properties of the elastomer such as for example elongation an break, modulus, compression set and heat buildup. Furthermore, good processing safety during the mixing of the elastomer with the filler and the coupling agent is also highly sought.

- Example 1 Preparation of 3-(3-triethoxy-silanyl-propylsuIfanyl)-propionic acid iso-octyl ester (compound 101).
- a dry reaction flask is flushed with nitrogen and charged with 7.6 g of sodium hydride (60% in mineral oil, 0.19 mol) and washed with ⁇ O ml of hexane.
- the hexane phase is carefully decanted and 150 ml of DMF is added.
- 44 g (0.2 mol) of 3-mercapto- propionic acid iso-octylester is dropped at 10 - 1 ⁇ °C to the stirred sodium hydride suspension.
- reaction mixture After stirring at room temperature for 1. ⁇ hours, the reaction mixture is cooled again to 10°C and 48.1 g (0.19 mol) of 3-chloropropyl-triethoxy- silane is added within 5 minutes. The reaction mixture is heated to 50°C and stirring continued for 17 hours. The reaction mixture is cooled to room temperature and filtered using a glass sinter funel. The filtrate is evaporated and the liquid residue fractionated using high vacuum. The compound 101 is obtained as clear liquid having a boiling range of 146 -1 ⁇ °C (0.08 mbar).
- Example 2 Preparation of 3-(3-trimethoxy-silanyl-propylsulfanyl)-2-methyl-propionic acid methyl ester (compound 106).
- Example 7 Coupling of silica in a styrene-butadiene rubber.
- a basic compound containing 100 parts of SSBR [SSBR Nipol NS 210 (RTM); styrene-butadiene rubber from Nippon Zeon/Japan], 2.5 parts of ZnO and 1.5 parts of stearic acid is mixed on an open two roll mill at 60°C.
- the incorporation of the coupling agent according to Table 4 and the coupling reaction with 35 parts of silica silica [Ultrasil VN3 (RTM) from De- gussa] is conducted in a Brabender laboratory mixer with cam blades at 145°C. The torque at the cam blades and the stock temperature is recorded continuously.
- the curing system is subsequently added on the two roll mill at 60°C.
- the Rheometer curves are measured at 150°C.
- Rubber samples for testing are compression molded to T9 ⁇ of the Rheometer curve at 160°C.
- Tensile test with ISO S 2 dumb-bells (DIN 63 604). Heat build up (Goodrich flexometer) according to ASTM D 623; and Compression set (recovered height) according to DIN 63 517.
- the elongation at break and the modulus 100 of the tensile test, the sample temperature after the Flexometer test and the recovered height are indications for coupling efficiency.
- the recorded torque during the Brabender mixing procedure and the TS2 value of the Rheometer curve indicates the scorch resistance of a coupling agent.
- the compounds of the formula I fulfil the high criteria as coupling agents for silica in a styrene-butadiene rubber. The results are summarized in Table 4. 63
