    Abstract: Propylene polymers (I) contain a matrix of propylene homopolymer and a copolymer of propylene and other alkenes. The novelty is that the polymers satisfy certain condition(s) when separated by tacticity and comonomer distribution of the polymer chain. They are first dissolved in boiling xylene, then the solution is cooled to 25 degrees C at a rate of 10 degrees C/hour. The polymers are separated, into fractions of different solubility at increasing temperature, whilst the matrix remains undissolved on heating the cooled solution to 80 degrees C. The conditions are that the amount of matrix remaining undissolved on further heating is (i) > 20 wt.% at 112 degrees C; (ii) > 8 wt.% at 117 degrees C and/or > 1 wt.% at 122 degrees C. Also claimed are (1) a method of producing (I); and (2) films, fibres or mouldings made from (I).
