Definitions
- the invention relates to suspension copolymers of methyl methacrylate and other monomers which can be copolymerized therewith and which have a high content of residual peroxides not previously achieved.
- the beads according to the invention with an increased residual peroxide content can be used, for example, in construction chemistry as a polymerization initiator in or redox-curing binders.
- EP 581 387 (Bristol-Myers Squibb Company) describes a bone cement which is made up of polymer particles, the polymer particles consisting of several layers which can contain a wide variety of additives. In addition to X-ray contrast agents, dyes, antibiotics, bone growth factors, the layers can also contain polymerization initiators. The polymer particles are always built up in layers. Different polymerization kinetics are achieved by distributing the polymerization initiator over different, shell-shaped compartments (see FIG. 7 of EP 581 387). task
- the object was therefore to provide polymer beads with different compositions of the starting monomers and as high a content of homogeneously distributed polymerization initiator as possible, which do not require the complicated shell-like structure and are thus easier and cheaper to produce.
- the beads should also have a large processing latitude in monomer-containing free-radically curable reactive resin systems, so that the pot life should be as large as possible.
- the ratio of peroxide concentration to polymer and the solubility of the beads in the reaction resin can be used to control the open time that is available for processing the reaction resin.
- composition of the beads according to the invention is composition of the beads according to the invention:
- R 2 methyl, ethyl
- R 3 H or CH 3
- R 4 an aliphatic radical with 4-6 carbon atoms, such as: n-butyl, isobutyl, t-butyl, pentyl, hexyl and methyl
- 3-10% by weight of a peroxide or a peroxide mixture are preferred. 5-10% by weight of a peroxide or a peroxide mixture are particularly preferred
- Benzoyl peroxides and other diacyl peroxides are used as the peroxide or peroxide mixture.
- copolymerizable monomers used are styrene or styrene derivatives, such as methylstyrene or maleic acid or maleic anhydride.
- the beads have an average diameter of 50 to 200 ⁇ m.
- the diameter was determined by means of laser diffraction spectroscopy with a Mastersizer Microplus from Malvern (measuring range: 0.05 - 555 ⁇ m).
- the residual monomer content was measured using gas chromatographic headspace analysis, a method for determining evaporable constituents in liquids and solids (including monomers in thermoplastics).
- the viscosity number VZ (also Staudinger function) is the concentration-related relative viscosity change of a 0.5% solution of the copolymer in chloroform based on the solvent, whereby the throughput times in the Ubbelohde viscometer with hanging ball level, Schott type no. 53203 and capillary 0c according to DIN -Norm 51562 at 25 ° C were determined. Chloroform was used as the solvent.
- copolymers to be used according to the invention are known per se. They can be produced in bulk or suspension polymerization. Helpful hints can be found with regard to substance polymerization in Houben-Weyl, Volume E20, Part 2 (1987), page 1145 ff. Die
- Production instructions for the depot peroxide pearl 37.75 g of aluminum sulfate x 14 H 2 O were dissolved in 3750 g of deionized water and heated to 40 ° C. in a 51 polymerization vessel equipped with a stirrer, reflux condenser and thermometer. To produce the suspension stabilizer, 166.25 g of a 10% strength aqueous sodium carbonate solution, 0.28 g of sodium cis paraffin sulfonate and 0.272 g of polyethylene glycol (molecular weight 5,000-6,000) were added with stirring.
- the activated reaction resin was then poured onto a concrete base in a layer thickness of approx. 2 mm. It cured tack-free within about 30 minutes and had a pot life of 15 to 18 minutes.
- Example 2 The experiment of Example 2 was repeated, but as a starter 2%
- Degadur 523 (DGD 523) is marketed by Röhm GmbH & Co. KG and is a reaction resin that is manufactured on the basis of low-boiling monomers.
- Degadur 523's monomer phase consists of methyl methacrylate, 2-ethylhexyl acrylate and polyfunctional methacrylates.
- NGB52 is a reaction resin based on medium boiling monomers (e.g. butyl methacrylate).
- GFG 330 HS is a reaction resin based on high-boiling monomers, such as B. tetrahydrofurfuryl methacrylate.
- the pot life appears in the first place, the curing time in the second place.
- the pot life should be between 50 and 20 minutes, the curing time between 25 and 60 minutes.
- the coating composition is a homogeneous mixture that is easy to apply.
