Definitions
- the invention relates to a process for the preparation of linear polymers or block copolymers of styrene by anionic polymerization of styrene and optionally butadiene in an inert, non-polar solvent in the presence of organolithium initiators and subsequent termination of the "living" polymer chains.
- the invention was therefore based on the object of suppressing this deposit formation. It has been found that this object is achieved if an n-alkyl glycidyl ether or a dialkyl ketone is used as the chain terminator.
- the invention accordingly relates to a process for the preparation of linear polymers or block copolymers of styrene by anionic polymerization of styrene and, if appropriate, butadiene in an inert, nonpolar solvent and subsequent termination of the "living" polymer chains by an n-alkylglycidyl ether or by a dialkyl ketone.
- Block copolymers consist of several polymer blocks, e.g. Polystyrene, polybutadiene and butadiene / styrene copolymer blocks.
- the latter can be statistical copolymers or e.g. around "tapered" copolymer blocks in which a polybutadene sequence is first formed, into which more and more styrene is incorporated as the polymerization progresses, so that a polystyrene sequence is finally formed. In all cases there is a lithium atom at the end of the chain that must be terminated.
- the anionic polymerization is carried out in an inert, non-polar solvent, preferably in cyclohexane.
- Preferred organolithium initiators are n-butyllithium and sec-butyllithium.
- the usual auxiliaries such as e.g. Ethers such as tetrahydrofuran, which act as activators for n-butyllithium and - used in larger quantities - as randomizers for the production of statistical copolymers, and potassium alcoholates, such as potassium tert. - amylate, which also act as a randomizer.
- the chain is terminated according to the invention by means of an n-alkylglycidyl ether or a dialkyl ketone.
- Preferred chain terminators are n-butyl glycidyl ether and diethyl ketone.
- the chain terminating agent is expediently used in stoichiometric amounts
- Lithium or used in a slight deficit, preferably in a molar ratio of 1: 1 to 1: 0.95. By using a small deficit it can be avoided that residues of the demolition agent remain in the polymer.
- alcohols preferably isopropanol or glycerol
- 1 to 99, in particular 5 to 50, moles of alcohol are preferably added to 100 moles of lithium.
- the lithium alcoholate formed is hydrolyzed. This can be done with organic or inorganic acids, preferably with CO 2 / H 2 O. Residual carbanions which are present when the chain terminating agent is deficient are also terminated.
- the lithium salt formed during the hydrolysis should be soluble or at least finely dispersible in the polymer solution so that the polymer remains transparent. This is the case with lithium carbonate, which is formed on hydrolysis with CO 2 / H 2 O.
- the polymer solution is stabilized as usual, e.g. with trisnonylphenylphosph.it, 2,6-di-tert-butyl -4-methylphenol, Irganox 1076 or Irganox 3052 (CIBA SC), and freed from the solvent by known degassing methods.
- Example 2 The polymerization was carried out as in Example 1, but 12 g of 10% isopropanol solution were added instead of butyl glycidyl ether for termination. The pale yellow solution was then acidified as above with 10 g dry ice (CO 2 ) and 5 ml water. It was colorless, but milky cloudy. After standing for one day, a voluminous white precipitate precipitated, which was identified as moist Li 2 C0 3 .
- the GPC measurement showed a bimodal molar mass distribution with maxima at 47,000 and 94,000 g / mol.
- the high molecular weight was 21%.
- Example 2 Analogously to Example 1, 12 g of 10% acetone solution were used instead of butyl glycidyl ether and worked up analogously. The solution was also water-clear afterwards, but colored deep brown-red. It didn't change over several days.
- the GPC measurement showed a bimodal molar mass distribution with maxi a at 47,000 and 94,000 g / mol.
- the high molecular weight was 25%.
- Example 5 The experiment was carried out as in Example 5, except that 0.9 g of isopropanol was added instead of butylglycidyl ether. After acidification with CO 2 / water, a colorless but very cloudy solution was obtained, from which a thick, fluffy precipitate precipitated out over the course of a day.
