This unsa tu ra ted organosi l icon "bui ld­

character is t ic of vinyl c o m p o u n d s . E a s e

of addi t ion to the vinyl double b o n d ,

suggests this silane as a new m e a n s of

in t roduc ing a silicon radical into var i ­

ous organic molecules .

Copolymer iza t ion of vinyl t r ichloro-

silane w i t h other vinyl monomers yields

po lymers which c a n be cross-linked by

hydrolysis a n d condensa t ion . Reac­

tions of the vinyl g roup wi th o the r

c o m p o u n d s can b e carr ied out e i ther

prior to, or after forming the silicones.

Vinyl tr ichlorosilane is one of m a n y

Wt(te to the New Products Division

W h e r e does all that whisky go? Not the gallons that are sold, but the 229i that can be expected to evaporate or be lost through leakage before maturity, ac­cording to industry spokesmen. When you consider that the total supplies of whisky in t he hands of distillers today add up to some 620 million gallons ( the biggest tota-I since 1933 and compares with about 578 million gallons a year ago ) , 22% is a quantity to be reckoned with. Come on, you slip-stick artists, figure out an answer for tha t one.

Corrosionproof

As an eye-stopper the announcement of the Corrosion Symposium held recently as a joint meeting of the San Diego sec­tions of the AMERICAN C H E M I C A L SOCIETY and t he American Society for Metals did the trick. It was printed on a sheet of thin-gage aluminum provided through the courtesy of the Kaiser Aluminum Co.

Leading industrial doctors advise immedi­ate washing with plenty of running water a s the best first a id treatment for any chemical in the e y e s . Records prove that wash ing with water for ten minutes or more, c l o s e to the accident, is n e c e s s a r y to reduce or eliminate e y e d a m a g e .
