Abstract: Disinfectant based on aq. polyvinyl pyrrolidone - I2 solns. contains added H2O2, pref. in concns. of 0.4-20 (2-10) wt.%/wt. total I2 and calculated as 100% H2O2. Available I2 content is increased. H2O2 addn. reduces iodide content, suppresses HI formation, re-converts iodide ions present to I2. Polyvinyl pyrrolidone may have K-value 15-100 (15-50). Total I2 content may be 5-20 % w.r.t. total polyvinyl pyrrolidone-I2 wt. Polyvinyl pyrrolidone-I2 may be used as 5-30 wt. % aq. solns. contg. 0.5-5 wt. % available I2. H2O2 may be used as solns. contg. 30-50 % H2O2.

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.
