Preparation Of Chlorinated Polyolefins
US Patent:
4524189, Jun 18, 1985
Filed:
Mar 20, 1984
Appl. No.:
6/591653
Inventors:
James B. Akers - Baton Rouge LA
Douglas E. Leng - Midland MI
Randall J. Normand - Plaquemine LA
Douglas E. Leng - Midland MI
Randall J. Normand - Plaquemine LA
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C08F 822
US Classification:
525 35G
Abstract:
Method and apparatus for the chlorination of polyolefins in aqueous suspension. The method includes subjecting the suspension of the polyolefin to a submerged jet of chlorine gas at a velocity sufficient to atomize the chlorine; i. e. , at least about sixty feet per second. By this method a very intimate mixture of chlorine and aqueous suspension is formed, whereby the chlorination proceeds more efficiently and at a lower chlorine pressure. Further advantages include a more uniformly-substituted product.

Drying And Removing Residual Acid From Halogenated Polymer Resins
US Patent:
4730035, Mar 8, 1988
Filed:
Sep 4, 1986
Appl. No.:
6/903635
Inventors:
Frank E. Mark - Schaferstieg, DE

James B. Akers - Baton Rouge LA
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C08F 600
US Classification:
528502
Abstract:
Moist halogenated resins separated from an aqueous acid suspension of said resins are dried and stripped of residual acid with a heated inert drying gas. The resins are not washed to lower residual acid or treated with a base compound to neutralize residual acid before drying begins. Inert drying gases include nitrogen, helium, argon and the like. The dried resin has low residual acid and moisture levels. It is white and free of visually detectable areas of discoloration. It also has high thermal stability, particularly when admixed with minor amounts of a thermal stabilizer such as calcium stearate.
