<p>Silatrane containing particles (A) comprise at least a rubber and 55-99 wt.% of silatrane compound (I). Silatrane containing particles (A) comprise at least a rubber and 55-99 wt.% of silatrane compound of formula (I). R : aryl or aralkyl (both optionally substituted), H, cyclic 1-12C alkyl, or COOH; R1 : aliphatic/aromatic divalent 1-30C hydrocarbon; A : -SH, -NH 2, -SCN, -Cl, -H, -OR2, -NHR2, -NR2 2, -CH=CH 2, -S-C(O)-R2, -S-C(O)-N(R2) 2, -S-C(S)-N(R2) 2 or 2-S x-; R2 : aryl or aralkyl (both optionally substituted), H or cyclic 1-18C alkyl; a : 1 or 2; and x : average sulfur chain length of 1.1-5. Independent claims are included for: (1) producing (A) comprising mixing 55-99 wt.% of (I) and rubber, and subjecting the mixture to a shaping process; and (2) producing a rubber mixture comprising mixing at least a rubber, at least a filler and (A).
