Abstract

As solvents for synthetic resins, in particular for the condensation products of polyvinyl alcohols with aldehydes, are employed the cyclic acetals obtained by the action of ethylene glycol or ethylene oxide or their homologues or formaldehyde or acetaldehyde or their polymers in the presence of a mineral acid or a metallic halide. In examples: (1) ethylene glycol and trioxymethylene are heated with phosphoric acid; the product is a solvent for the condensation products of polyvinyl alcohol with formaldehyde, and may be used for the production therefrom of varnishes, films, transparent sheets for packing and plastic materials in blocks, sticks or tubes; (2) acetic paraldehyde is used in place of trioxymethylene; the product is a solvent for the mixed condensation products of polyvinyl alcohol, formaldehyde and acetaldehyde. Specifications 409,507 and 430,136 are referred to.
