Abstract:
An oligomeric silane treated metal hydroxide product for use in a polymeric composition comprising a plurality of ground metal hydroxide particles and an oligomer of the formula ##STR2##whereinn is an integer of from 0 to 8, inclusive,R is independently alkenyl (e.g. vinyl), alkoxy, alkyl, or isoalkyl of 1 to 18 carbon atoms,provided however that each silicon atom has no more than one alkenyl substituent attached thereto, and the molar ratio of alkenyl to alkoxy substituents is 1:1 to 1:8, and the molar ratio of alkenyl to alkyl substituents is 1:0 to 1:8, and the alkenyl content of the oligomer is between 6 and 12 weight percent;said ground metal hydroxide particles being surface treated by said oligomer.
