Abstract: Thermoplastic moulding compsn. consists of (A) 99-50 wt.% copolymer of 90-96% vinylidene chloride (VDC) and 10-4% 1-6 C alkyl acrylate and (B) 1-50% copolymer of 80-85% VDC and 20-15% 1-6 C-alkyl acrylate, and the compsn. is esp. suitable for the prodn. of films and coatings on films or paper, esp. film blowing, melt coating and laminated film prodn.

Abstract: Vinylidene chloride (I) copolymers, which are easy to process to a film, are produced by discontinuous polymerisation of a mixt. of 90 - 94 (wt.) % 1,3 - 4% 2-ethylhexyl acrylate (II) and 2 - 6% 1 -5C-acrylate (III). The copolymer has good extrusion qualities and no plasticers or stabilisers are needed to improve its processability. It is suitable for extrusion and esp. for making blow moulded films, which can be heat sealed and used in shrinking-on applications. It can also be used for melt coating paper etc. The copolymer pref. is prepd. by suspension polymerisation, using the total amt. of II and only part of I and III in the initial charge.

Abstract: Stable, liquid, homogeneous solutions of isocyanurate-polyisocyanates containing amide and/or acylurea groups in monomeric diisocyanates and/or polyisocyanates which are free from amide, acylurea and/or isocyanurate groups, are obtained by reacting polybasic carboxylic acids with diisocyanates and/or polyisocyanates to give diisocyanates and/or polyisocyanates containing amide groups and/or acylurea groups, converting the diisocyanates and/or polyisocyanates containing amide and/or acylurea groups by trimerization and, optionally, polymerization, into isocyanurate-polyisocyanates containing amide and/or acylurea groups, and mixing the products with monomeric diisocyanates and/or polyisocyanates.

Abstract: Ternary polymers of 80-90 wt.% vinylidene chloride, 1-4% acrylonitrile and 2-9% 1-8 C-alkyl acrylate units, produced by discontinuous suspension polymsn., are used for blowing films. The impervious films can be produced without the addn. of plasticiser or stabilisers and hence are suitable for packaging foodstuffs.
