Abstract: In order to improve the resistance to the formation of stress cracks in hollow elements made from thermoplastics, the surfaces of the hollow elements are nitrosochlorinated and subsequently thermally crosslinked. The nitrosochlorination can be carried out either in the gas phase or in suspension and is preferably initiated photochemically.

Abstract: In order to prepare thermoplastic polyurethane elastomers (a) organic diisocyanate, (b) polyhydroxyl compounds with molecular weights of 500 to 8,000, and (c) chain extenders with molecular weights of 60 to 400 in the presence of (d) catalysts, and optionally (e) auxiliaries, and/or (f) additives are reacted in two reaction stages at temperatures from 60 DEG C. to 250 DEG C. In the first reaction stage the components are continuously mixed, the reaction mixture is applied to a carrier, preferably a conveyor band of thermoplastic material, and is allowed to react at the reaction temperature until solidified. Subsequently, the solidified reaction mixture is melted in an extruder and the reaction is completed in the second reaction stage.

Abstract: Non-sticky, highly elastic, multifil polyurethane elastomer thread (I) is produced by the melt-spinning process, using a plasticiser-contg. thermoplastic PU material (II) consisting of (A) 99-50 pts. wt. thermoplastic PU with Shore A hardness 95-80, main melting peak (hard segments) at 210-220 deg.C (by DSC) and MFI 0.1-200 (190 deg.C./212 N) and (B) 1-50 pts. wt. di(methoxyethyl) phthalate, tricresyl phosphate and/or diphenylcresyl phosphate as plasticiser; (A) is obtd. by reaction of (a) organic di-isocyanates with (b) mainly difunctional polyhydroxy cpds. with mol. wt. 500-8000 and (c) chain extenders with mol. wt. 60-400 in the presence of (d) catalysts and (e) opt. auxiliary substances and/or additives. (I) is claimed as such, with elongation at break above 300% (DIN 53815) and strain ratio above 0.85. Pref. Shore A hardness is 60-80; (a) is 4,4'-diphenylmethanedi-isocyanate (MDI) or 1,5-naphthylenedi-isocyanate, (b) are linear polyester-ols obtd. from adipic acid and 2-6C alkanediols, polycaprolactones and/or polytetramethylene-ether glycols and (c) is 1,4-butanediol. USE/ADVANTAGE - (I) is useful for the prodn. of textile fibres or plane textile structures (claimed). Applications are in the textile industry (outer clothing, corsetry, etc.), bandages, reinforcing fibres for plastics, etc. The process enables the prodn. of highly-elastic multifilament PU thread which is non-sticky.
