Abstract
Abstract A copolymeric reaction product consisting essentially of (A) 60 to 95 percent by weight of a resin consisting essentially of 45 to 72 mole percent SiO 2 units and 28 to 55 mole percent (CH 3 ) 3 SiO 1/2 units, and (B) 5 to 40 percent by weight of a resin consisting essentially of 60 to 100 mole percent RSiO 3/2 units, 0 to 35 mole percent R 2 SiO units and 0 to 5 mole percent R 3 SiO 1/2 units, each R radical being independently selected from the group consisting of the methyl, propyl and phenyl radicals, is disclosed. These siloxane copolymers can be combined with a trimethylsilyl endblocked polydimethylsiloxane fluid and conventional organic thread finishes to obtain thread treating compositions.
