Description
Reinforced Impact Modified Polycarbonates
This invention relates to thermoplastic molding composi¬ tions having improved notched Izod impact strength comprising
(a) a bisphenol-A polycarbonate;
(b) at least one reinforcing agent selected from the group consisting essentially of glass fibers, glass beads, and mix¬ tures of glass fibers and glass beads, in admixture with;
(c) a minor amount of at least one component selected from the group comprising polyolefins, olefin based copolymers and olefin based terpolymers, such as ethylene-propylene copolymers, ethylene-butadiene copolymers, propylene-butadiene copolymers, ethylene-propylene-butadiene terpolymers, ethylene-acrylic acid copolymers, propylene-acrylic acid copolymers, ethylene-ethyl acrylate copolymers, ethylene-vinyl acetate copolymers and ethylene-propylene-acrylic acid terpolymers. Background of the Invention
The use of bisphenol-A polycarbonates as molding composi¬ tions, both with and without reinforcing agents is well known and these materials have been widely employed in the manufacture of various thermoplastic molded articles. In the preparation of such bisphenol-A polycarbonates for use as molding compositions, one may employ a variety of rein¬ forcing agents in various amounts which improve the flexural properties of the molded article in proportion to the amount of such material employed.
It has now been found that the incorporation of a relative¬ ly minor amount of at least one component selected from the group comprising polyolefins, ethylene-propylene copolymers, ethylene-butadiene copolymers, propylene-butadiene copolymers, 5 ethylene-propylene-butadiene terpolymers, ethylene-acrylic acid copolymers, propylene-acry1ic acid copolymers, ethylene-ethyl aerylate copolymers, ethylene-vinyl acetate copolymers, ethylene- propy1ene-acry1ic acid terpolymers and olefin based copolymers and terpolymer elastomers, in admixture with a quantity of at 0 least one reinforcing agent selected from the group consisting essentially of glass fibers, glass beads, and mixtures of glass fibers and glass beads into a bisphenol-A polycarbonate will significantly improve the notched Izod impact strength charac¬ teristics of the resultant polycarbonate molding composition 5 over those which could be realized via the use of glass fiber or glass bead reinforcing agents alone. Description of the Invention
The present invention provides for a novel thermoplastic molding composition which comprises Q (a) a bisphenol-A polycarbonate;
(b) at least one reinforcing agent selected from the group consisting essentially of glass fibers, glass beads, and mix¬ tures of glass fibers and glass beads, in admixture with; -
(c) a minor amount of at least one component selected from the 5 group comprising polyolefins, olefin based copolymers and olefin based terpolymers, such as, ethylene-propylene copolymers, ethylene-butadiene copolymers, propylene-butadiene copolymers, ethylene-propylene-butadiene terpolymers, ethylene-acrylic acid copolymers, propylene-acrylic acid copolymers,^ethylene- ethyl acrylate copolymers, ethylene-vinyl acetate copolymers and ethylene-propylene-acrylic acid terpolymers.
The polycarbonate resin has recurring units of the formula
wherein each -R- is selected from the group consisting of phenylene, halo-substituted phenylene and alky! substituted phenylene, and X and Y are each selected from the group consist¬ ing of hydrogen, hydrocarbon radicals free from aliphatic unsaturation and of radicals which together with the adjoining
atom form a cycloalkane radical, the total number of carbon.atoms in X and Y being up to 12.
The preferred polycarbonate resins may be derived from the reaction of bisphenol-A and phosgene. These polycarbonates have from 10-400 recurring units of the formula:
-
The polycarbonates are described in U.S. Patents Nos.
3,028,365; 3,334,154 and 3,915, 926 all of which are incorporated by reference. The polycarbonate should have an intrinsic vis¬ cosity between 0.2 and 1.0, preferably from 0.30 to 0.65 as measured at 20°C in methylene chloride.
Although it is only necessary to use a reinforcing amount of the reinforcing agent in the compositions of the present invention, from 1-60 parts by weight of the total weight of the resultant molding composition may comprise the reinforcing 5 agent. A preferred range is from 5-40 parts by weight.
The preferred reinforcing agents for use in the present invention are of glass, and it is preferred to use fibrous glass filaments, glass beads, or mixtures of these. The pre¬ ferred glass filaments for plastics reinforcements are made ° by mechanical pulling, and have filament diameters in the range of from about (0.000112) 0.000284cm to about (0.00075 inch 0.0019cm. However, this is not critical to the present inven¬ tion.
The glass beads which may be advantageously employed either 5 alone or together with the treated glass fibers described above will have diameters on the order of 0.0003cm (0.0001) to about .0.025cm (O.OlOinches) and are generally prepared via spraying of the molten glass as fine droplets into liquid baths.
The glass fibers may be employed in amounts up to about 0 40 parts by weight of the total composition and the glass beads may be employed in amounts up to about 60 parts by weight of the total composition. The glass fibers and glass beads may be advantageously employed in varying proportions such that the combined quantity of glass fibers and glass beads make up from 5 about 1 to about 60 parts by weight of the total composition. The preferred range of the combined glass fibers and glass beads is from about 5 to about 40 parts by weight of the total mold¬ ing composition.
The polyolefin copolymers , such as ethyl ene-propylene ' copolymers , and olefin terpolymers , such as ethylene-propylene- butadiene terpolymers, which may be suitably employed in practicing the present invention are all commercially available products whose preparation is well known.
The olef in-acrylic acid copolymers , such as ethylene- acryl ic acid copolymers , and di olef in-acrylic acid terpolymers , such as ethyl ene-propylene-acryl ic acid terpolymers and other olefin based thermoplastic elastomers , which may be suitably employed in practicing the present invention are also commercial¬ ly available products whose preparation is well known, as will be readily apparent to those skilled in the art.
