Definitions
- the invention relates to high-impact polymer alloys based on polyamides, which have a rel. Have a viscosity of at least 3; 5 or a k-value of at least 83 (according to Fikentscher).
- the impact strength of moldings made of polyamide plastics depends considerably on the water content of the moldings.
- those made from easy-flowing polyamide injection molding compositions with a medium molecular weight, and here again the shaped bodies made from highly crystalline polyamides are relatively sensitive to impact stress.
- the impact strength of polyamides is improved by adding polymeric substances.
- Polyethylenes and copolymers of vinyl acetate and ethylene have been used with moderate success.
- polyamide alloys with particularly high notched impact strength are obtained when freshly sprayed if polyamides, in particular 6-polyamides, with a rel.
- 6-polyamide is preferably used as the polyamide ven viscosity of at least 3.5 used.
- using the hydrophobic and non-polar alloy partners mentioned 2) show 6-polyamides with a rel. Viscosity of at least 3.5, preferably at least 3.8, a compared to analog alloys based on 6-polyamides with the viscosity that is common in practice for the injection molding sector ( ⁇ rel approx. 3.0), a drastic improvement in the impact strength, as was previously the case in this ratio only with water, which is known to be partly built into the hydrogen bonds of the polyamide, was possible.
- the notched impact strength can be doubled under normal conditions using high-molecular 6-polyamide compared to the normally viscous 6-polyamide.
- Polymers of aliphatic monoolefins with C 2 -C 4 in particular polyethylene or polyethylene / polypropylene copolymers, preferably with melt indices in the range from 5 to 20 cm / 10 min (190 ° C.) are preferably used as polymer component 2a.
- All or part of the (meth) acrylic acid can be present as a salt, preferably as a sodium or zinc salt.
- the copolymers 2c) used are preferably copolymers of styrene, (meth) acrylic acid and (meth) acrylic acid esters with C 4 -C 10 , preferably C 4 -C 7 in the alcoholic component, particularly preferably n- or tert-butyl ester.
- Suitable polymers according to 2d) are preferably high molecular weight polybutadienes and polyisoprenes, as well as copolymers of butadiene and / or isoprene with acrylonitrile, the proportion of acylnitrile preferably being 10-30 mol%.
- the alloys can be produced by mixing the starting components at temperatures above the melting point of the polyamide used, advantageously at temperatures of 200-320 ° C., in particular at 260-290 ° C.
- Devices in which the molding compositions according to the invention can be produced are conventional screw machines.
- thermoplastic molding compositions can also incorporate stabilizers, mold release agents, lubricants, crystallization accelerators, plasticizers, pigments, dyes or fillers, such as glass fibers or asbestos.
- Moldings made from the polymer alloys according to the invention have a relative to alloys based on 6-polyamides. Viscosity ⁇ 3.5 the same homogeneity and show no tendency to segregate. They show good surface properties and, compared to moldings made from pure polyamides, have a reduced water absorption.
- the molding compounds are particularly suitable for extruder and injection molding processing for the production of various high-impact molded articles, among others. also Pohren.
- the relative viscosity of the polyamides is measured on a 1 solution of the polymer in m-cresol at 25 ° C.
- Example 1 In contrast to Example 1, a 6-polyamide with a rel. Viscosity of 3.0, measured as used in Example 1. The - as described in Example 1 - mixed components are extruded at 26 ° C. The product has a rel. Viscosity ⁇ rel of approx. 3.2, determined according to Example 1. Freshly sprayed test specimens show Alternating bending tests have excellent homogeneity and have a notched impact strength of 12 kJ / m 2 (DIN 53 453).
