(for example block or graft copolymer) or mixtures thereof which contain at least 85 weight per cent of polyacrylonitrile and up to 15 weight per cent of one or more polymerized and compatible ethylenically unsaturated monomers; the term " filaments " is defined to include monofilaments, fibres...
Monoacrylate urethane monomers which are compatible with polyamide type materials can be cited for example. Insofar as the invention enables less reactive mixtures to be used, these mixtures can be more economical than those used hitherto in a direct process. For example, light primers, a term...
solid state drawing). An orientable polymer can be amorphous or semi-crystalline (semi-crystalline polymers have a melt temperature (Tm) and include those polymers known as “crystalline”). Desirable orientable polymers include semi-crystalline polymers, even more ...
Then, the temperature of the reaction mixture was raised to 100° C., followed by stirring for one hour, thereby distilling off the unreactedmonomers. After cooling the reaction mixture, it was passed through a nylon cloth of 200 mesh. The resulting white dispersion was a latex having a ...
Suitable propylene block copolymers contain predominantly, i.e., more than 50 weight-percent, preferably 70 to 99 weight-percent, in particular 90 to 99 weight-percent propylene units. Suitable comonomers in corresponding quantities are ethylene, butylene, or higher alkene homologs, among which ethyl...
Suitable PP-based polymers include Zeigler Natta, metallocene and post-metallocene prolypropylenes. Suitable PP-based polymers include PP homopolymer; PP random copolymer (with ethylene or other alpha-olefin present from 0.1 to 15 percent by weight of monomers); PP impact copolymers with either PP...
