    Abstract: Milling of a Ti cpd. (I) of formula TiCl3.nAlCl3 (where n is 0.01-1) and a 2-34C ester (II) of formulae R10-C(O)R2 or R10-C(O)-CR2=CHR2 (where R1 is 1-16C alkyl or 7-23C phenylalkyl where phenyl gp. is opt. substd. R2 is H, 1-18C alkyl, 7-23C phenylalkyl where phenyl gp. is opt. substd. by 1-4C alkyl, phenyl or 7-23C alkyb phenyl is carried out (1) at a milling acceleration of 30-80 m/sec-sec, (2) filling the mill first with (I) and opt. milling at -50 to 100 deg.C for 0.5-100 hrs. in the absence of diluant, (3) adding (II) in the absence of diluents continuously or in small amts. at -50 to 80 deg.C in a mol. ratio of Ti in (I) to (II) of 1:1.5-1: 0.1 at a rate of 0.01-200 ml/min per 2.5 (I), (4) milling for 1-120 hrs. at 15-100 deg.C, (5) opt. milling for 0.5-60 min. at -50 to 5 deg.C in the absence of diluants, (6) opt. maintaining the prod. from step (4) or (5) at 20-150 deg.C for 0.25-300 hrs. without milling and (7) opt. past-milling the prod. from step (6) for 0.5-60 min. at -50 to 5 deg.C in the absence of diluant, a suspension is formed from 1 pt.wt. the prod. obtd. from steps (4), (5), (6) or (7), 0.5-20 pts.wt. hydrocarbon with a b.pt. below 150 deg.C and which is liq. an ambient conditions and an ether (III) of formula R8-O-R8 (where R8 is 1-15C alkyl, phenyl or 7-14C alkylphenyl and/or 2-34C ester (IV) of formulae R3- R3-OC(O)-R4 or R3-OC(O)-C(R4)=CH(R9) (where R4 is H, 1-12C alkyl, 7-14C phenylalkyl with one alkyl substituent, phenyl or 7-14C alkylphenyl and R3 is 1-8C alkyl, phenyl of 7-14C phenyalkyl) such that the mol ratio of Ti from (I) to (III) or (IV) is 1:0.01-1.2. The suspension is maintained under vigorous stirring at 40-140 deg.C for 5-120 min and then at 15-25 deg.C, opt. separating off the solids, washing with a hydrocarbon liq. at ambient conditions and a b.pt. below 150 deg.C, drying and isolating the Ti component. The polymers have high stereoregularity and good morphological properties.

    Abstract: TiCl3 componens for Ziegler-Natta polymerisation catalysts are prepd. by (1) wetting a standard catalyst component consisting of or contg. TiCl3 with hydrocarbon mixt. contg. (A) 100 pts. vol. pentane, hexane and/or heptane and (B) 10-1000 pts. wt. benzene or alkylbenzene having b. pt. 80-270 degrees C under standard conditions, provided catalyst component: wetting hydrocarbon mixt. is 1: x (where x is no. 0.01-0.5) and (2) drying under constant mixing. The catalyst components are used in alpha-olefin polymerisation, in gas- or liq. phase. The polymers have optimum morphological properties, e.g. narrow grain-size distribution. Catalyst component conditioning suppresses the formation of very fine grains having dia. 200 mu. Alkaline (A) is esp. n-hexane or n-heptane. The benzene hydrocarbon (B) is esp. toluene, a xylene or ethylbenzene. (B) can be a light oil mixt. having b. pt. 80-170 degrees c. Drying can take place (a) under an inert gas, in a rotary evaporator, for 0.5-5 hrs., under pressure 0.9-1.1 bar, at 5-50 degrees C above the highest-boiling hydrocarbon b. pt., or (b) in a ball mill under increasing vacuum.

    Abstract: catalyst component is prepd. by (1) contacting a finely divided carrier (I), with a soln. (II), prepd. by mixing (IIa) 100 pts. wt. alcohol having formula Z-OH (where Z is a satd. 1-8C hydrocarbyl (IIb) 0.01-6 pts. wt. (calculated as Ti) of a Ti trihalide (where halogen is Cl and/or Br) and (IIc) 0.01-4 pts. wt. (calculated as Mg) of an Mg cpd. soluble in (IIa), to form a dispersion (III). Wt. ratio (I):Ti in (IIb) is 1:0.01 to 1:0.2. Wt. ratio (I):Mg in (IIc) is 1:0.01 to 1:0.25. The dispersion (III) is evaporated to dryness, below 200 degrees C but above m.pt. of (IIa), to form a solid-phase intermediate prod. (IV). this is followed by (2) contacting with a metal cpd. (V) dissolved in an organic solvent, to form a dispersion. (V) has formula MtGs-tEt (where Mt is Al or Si; G is 1-12C hydrocarbyl; E is Cl, Br, I, H or -OD; D is a 1-12C hydrocarbyl; s is valency of Mt and t is I to s-1 when Mt is Al or 0.4 when Mt is Si). Wt. ratio (IV):(V) is 1:0.05 to 1:2. The resulting dispersed solid-phase prod. (VI) is the Ti-contg. catalyst component. The Ziegler catalyst systems are used in homo- and copolymerisation of 2-6C monolefins at 30-200 degrees C and 0.1-200 bar. Constant specific polymer yields are obtd. Polymer particles where high bulk wt. and fluidity. Polymer dust particle content is very small. Productivity, measured as polymer quantity/Ti, is high. Ti and halogen proportions in polymer are so small as to obviate a purifying step.
