Processes for producing dry powders from tacky polymers via dispersion of same in water with dispersants convertible to parting agents |
| abstract |
Processes are disclosed for comminuting and recovering as dry powders tacky ethylene-vinyl acetate (EVA) copolymers and tacky partially-hydrolyzed ethylene-vinyl acetate (HEVA) copolymers. The copolymers are comminuted by dispersion in water with an alkali metal soap of a higher carboxylic acid. Chemical conversion of the soap after dispersion to the alkaline earth metal soap or to the higher carboxylic acid permits recovery of the tacky copolymers as dry powders. The compaction resistance of the higher carboxylic acid-coated particles is improved by chemically converting deposited acid to the alkaline earth metal soap or by adding supplemental preformed alkaline earth metal soap. |
