Abstract: Free-flowing chloropolyethylene in powder form which keeps this property after prolonged storage and has good processing properties is impregnated substantially on the particle surface with definite amounts of fine-grained vinyl chloride polymer and fine-grained organic substance in a definite proportion. The invention also relates to a process for the manufacture of such an improved chloropolyethylene and the use thereof.

Abstract: New 3,3-diphosphono-pimelic acid and its derivs. have the formula (I): (R2O3P)2C(CH2-CH2-COOR)2 (I) (where R, which are opt. identical, are opt. halogen-substd. 1-18C alkyl gps., H, alkali- or NH4 ions). In pref. (I), the alkyl gps. are 1-3x substd. by halogen, esp. Cl and/or Br; alkyl gps. contain 1-8C and alkali ions are Na and/or K ions. (I) where R are only opt. halogen-substd. alkyl are used as plasticisers for PVC and also impart flame-resistant or self-extinguishing properties. (I) where R are only H, alkali and/or NH4 ions are used as (i) retarders for gypsum setting and (ii) complex-formers for metal ions, e.g. Fe and alkaline earth metals. Plasticiser concn. in PVC may be 20-50wt.%. Gypsum setting retarders are superior to citric acid and are used in 0.06-0.09wt.% concn. The complex-formers can be used for cleaning glass articles, e.g., in bottle washing compsns. In an example, 3,3-diphosphono-pimelic acid was prepd. by (i) reacting 4 mol. Et acrylate with 2 mol. tetra-Et methane-diphosphonate and (ii) acidolysis of the hexa-Et ester obtd.

Abstract: The compsn. which comes into contact with parental liqs. comprises 50-99.5 pt. wt. chlorinated polyolefin (I) with a Cl content of 15-45 wt. % and a mol. wt. of 3000-300000 and 0.5-50 pt. wt. poly(meth)acrylate. The compsn. has low water vapour permeability, high transparency, strength and good weldability and may be used for blood sacks, infusion tubes and packages and catheters.
