4. The resin contains "a plurality of silicon-bonded
hydroxy groups" (col. 2, lines 27-28).
5. For each mole of trialkyl silane used in the
cohydrolysis, there should be used from 1 to 2 mols,
advantageously about 1.2 to 1.8 mols of the alkyl silicate
(col. 4, lines 15-21).
6. The "fluid" is a "high viscosity organopoly-
siloxane" (col. 4, line 47) "having a viscosity within the range
of about 75,000 to 125,000 centiposes" (col. 6, lines 16-17),
which is treated so as to have "a terminal silicon-bonded
hydroxyl group" (col. 6, lines 30-31), and is further treated
"to obtain a higher viscosity material, for instance, one having
a viscosity of about 200,000 to 3,000,000 centipoises (col. 6,
lines 39-41).
7. The organopolysiloxane pressure-sensitive adhesive
is made by mixing the "resin" and the "fluid" under conditions
which permit "interaction [i.e., reaction,] between the" resin
and fluid (col. 6, lines 62-66).
8. The proportion of resin to fluid advantageously is
within the range of 0.5 to 6.0 weight parts of fluid per weight
part of resin (col. 7, lines 21-24).
9. In Table 1 of Example 1 there is described three
resin/fluid mixtures said to have been used to make pressure-
