-:;tr vinyl ethers may be obtained similarly. \r. interesting synthesis of taurine and X-methyltaurine from DCE was reported71
s.-.hich DCE and Xa,SO are condensed to sodium chloroethylsulphonate which
then animated with ammonia or methylamine. Taurine is a detergent intermedit. This work might well be restudied using modern aprotic solvents:
C1CH,.CH,C1 + XasSO, - ClCH!.CH,.SO,Na + NaCl

.vinyl chloride was the synthetic polymer produced in largest amount; in that
t it was surpassed by polyethylene. Production of both polymers is growing
r."id!y and the prediction has been made1 that PVC will resume the lead at least
.1 y.'.vk.vying as a result of the recent discovery that clear bottles can be made from
v. <hcr 3,000,000 tons are produced annually.
In view' of the great industrial importance of vinyl chloride, it was inevitable that
-T'-'jt deal of research should have been devoted to lowering its cost of production;
- itfort shows no sign of abatement and, in fact, the present situation must be
'.-;:hed as fluid, with five different raw materials: coal, natural gas, ethane,
.'iuha and gas oil and a multitude of processes competing for the market.
