摘要:This invention is directed to the preparation of certain arylene bis-silanols in highly purified form and to the preparation of five new arylene bis-silanols in particular, along with a procedure for polymerizing these and other arylene-type bis-silanols using phosgene as a polymerization promotor or catalyst, to obtain highly purified, high molecular weight arylene-siloxanylene polymers having the characteristic structure: ##STR1## where Y is an arylene or substituted arylene moiety; R and R' are the same or different alkyl group(s), substituted alkyl group(s) or a phenyl group, x ranges from about 1 to 3 and n ranges from about 300 to 1500, said polymers having molecular weights (number average) of 100,000 and higher. n Preferred polymers are those arylenesiloxanylenecarbonate polymers which, when laminated to polycarbonate sheets or glass maintain their transparency, stability and adherence to said substrates at temperatures of up to and including 400° F. Such polymers are useful for the formulation of high temperature interlayers for windshields and canopies for aircraft and related aerospace vehicles.

摘要:The invention relates to a method for producing polymerizates and copolymerizates of alpha -substituted acrylic compounds according to which one or more polymerizable monomeric compounds of general formula (I), wherein R<1> and R<2> assume the meanings as cited in the description, is/are polymerized, in the presence of a catalytically active structure, obtained in situ from an organometallic rare earth metal (III) complex or from a rare earth metal (II) complex of general formula (II): [(IND)A(IND)]LnR<6>, wherein: IND signifies a substituted indenyl group or a substituted cyclopentadienyl group with a fused aromatic or aliphatic ring; A represents a diyl radical which bridges two IND units and which comprises an element from groups 13, 14, 15 or 16 of the periodic table; Ln represents a rare earth metal in oxidation step +3 or +2, and; R<6> represents a hydride ligand or a ligand that is capable of forming agostic interactions, or represents a neutral donor ligand (e.g. tetrahydrofuran). The one or more polymerizable monomeric compounds is/are polymerized in an aprotic solvent for the catalytically active compound at temperatures ranging from -100 DEG C to the boiling point of the solvent. The polymerizate or copolymerizate obtained from the polymerization is, in an appropriate manner, isolated or subjected to an additional processing in solution. The invention also relates to the obtained polymerizates and copolymerizates which have a high isotacticity.
