of 0 or 1 g has the value of 0 and c has the value of 1 when a has the value of 3 g has the value of 0 and c has the value range of 1 to 5 when a has the value of 1 g has the value of 1 then c has the value of 1 when a has the value of 2 c has the value of 1 and g has the value range of 1 to 2 thus giving a molecular weight range of 221 to 2176 another specific example of this type of polysiloxane polyoxyalkylene copolymers is the copolymer having the general formula wherein me and g is as defined above and h has the average value range of 0 to 7 d has the average value range of 1 to 5 with the stipulation that when h has the value of 0 d has the average value range of 1 to 5 when h has the value range of 1 to 2 d has the value range of 3 to 4 when h has the value range of 3 to 4 d has the value of 1 to 3 when h has the value of 5 then d has the value range of 1 to 2 and when h has the value range of 6 to 7 d has the value of 1 the polysiloxane portion of the polysiloxane polyoxyalkylene copolymer has the preferred molecular weight range of 221 to 1 000 the molecular weight of the glycol portion is 103 to 500 grams per mole with 150 to 350 grams per mole being preferred for the purpose of this invention r in the general formulas defined above can be any hydrocarbon radical free of aliphatic unsaturation containing from.
