An efficient methodology for the synthesis of symmetrical methylene diesters was developed through direct reaction of various aromatic carboxylates with 1,n-dihaloalkanes under solvent-free conditions. This strategy offers a high product yield, facile work-up and purification, and an environmentally friendly approach to obtain long-chain methylene carboxylate scaffolds with increased diversity.

A reduced oil rubber composition includes (a) a silica filler, (b) a N-substituted polyalkylene succinimide derivative, and (c) a rubber matrix. In certain embodiments, the composition may comprise a reduced amount of oil, especially a reduced amount of aromatic oil or even no aromatic oil. Rubber articles manufactured from such composition, such as tires and power belts, have improved properties such as reduced rolling resistance, improved wet/snow traction and winter softness, improved dynamic stiffness, improved tensile strength, easy handling, and/or compatibility with higher environmental standard, among others.

Zusammensetzungen der Formel (I), worin R und R1 unabhängig voneinander Wasserstoff oder Methyl, R2 Alkyl und R3 Wasserstoff oder Alkyl bedeuten, wobei der Gehalt an Verbindungen der Formel (I) mit R = R1 = Methyl 80 bis 99 Gew.-% beträgt, eignen sich als Weichmacher für Kunststoffe und hier insbesondere für Homo- und Copolymere des Vinylchlorids, wie PVC.
