Abstract

1317044 Titanium halides MITSUBISHI PETROCHEMICAL CO Ltd 15 June 1970 [19 June 1969] 28835/70 Heading ClA [Also in Division C3] A modified titanium compound is prepared by mill processing a halogen compound of titanium of a valence lower than the maximum valence and an α,#-unsaturated carboxylate ester. In examples, titanium trichloride is milled with methyl methacrylate, cinnamate or crotonate, or butyl or 2-ethyl hexyl acrylate.
