Synthetic organosilane compounds useful as lubricants in glass sizing compositions

摘要

An aqueous glass fiber sizing composition acetate file former and an effective amount of a lubricant additive having the formula: <IMAGE> where R is an alkyl or alkenyl group of 6 to 20 carbons, A is a divalent organic-S-or-NH-group, R1 is an alkyl group of 1 to 4 carbons, m is or 1 and n is 0 to 10 with the proviso that when n is O, m is also O.
