Definitions
- thermoplastic molding composi ⁇ tions having improved notched Izod impact strength comprising
- polyolefins such as ethylene-propylene copolymers, ethylene-butadiene copolymers, propylene-butadiene copolymers, ethylene-propylene-butadiene terpolymers, ethylene-acrylic acid copolymers, propylene-acrylic acid cop
- 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.
- the present invention provides for a novel thermoplastic molding composition which comprises Q (a) a bisphenol-A polycarbonate;
- polystyrene resin has recurring units of the formula
- each -R- is selected from the group consisting of phenylene, halo-substituted phenylene and alky! substituted phenylene
- 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
- 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 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.
- 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.
- polyolefin copolymers such as ethyl ene-propylene ' copolymers

- propylene block copolymers al l of which are manufactured and sold by Hercules , Inc. :, US ⁇ LB 342 and USp-R.B 703, both ethylene homopolymers, manu ⁇
- compositions of the present invention may contain from about 0.5 to about 10 percent by weight of combined impact modifying component(s) described above, without taking into account the amount of reinforcing agents to be employed, and will preferentially contain from about 2 to about 6 percent by weight of the combined impact modifying component(s).
- compositions of the present invention may be prepared by any standard procedure and the particular method employed is not critical.
- the compositions of the present invention may also include flame retardants such as those described in U.S. Patent No. 3,915,926 which is incorporated herin by reference. Description of the ; 'Preferred Embodiments
- Example I Control A blend of 91 parts by weight of bisphenol-A polycarbonate and 9 parts by weight of chopped glass fibers was prepared, extruded in a twin screw extruder and molded into sample parts of approximately 0.3cm (1/8 inch) thickness. The results of impact and flexural tests on the resultant molded parts are set forth in Table I.
- Examples II - XXIII A blend of 91 parts by weight of bisphenol-A polycarbonate and 9 parts by weight of chopped glass fibers was blended with 4 parts per 100 by weight of various commercially available compositions as impact modifying agents as set forth in Table I. The various resultant blends were extruded and molded -in the • same manner as in Example I. The results of impact and flexur ⁇ al tests on the resultant molded parts are also set forth in Table I.
- V indicates that at least one sample did not fall when subjected to the machine l imit of 40 ft. -lb. /in.
- Exa ple XXIV - Control A blend of 60 parts by weight of bisphenol-A polycarbonate, 20 parts by weight of chopped glass fibers and 20 parts by weight of glass beads was prepared, extruded and molded into sample parts in the same manner as in Example I. The results of impact and flexural tests performed on the resultant molded parts are set forth in Table II.
- Examples XXV - XXX Blends of 60 parts by weight of bisphenol-A polycarbonate, 20 parts by weight of chopped glass fibers and 20 parts by weight of glass beads in admixture with 4 parts per 100 by weight of various compositions as impact modifying agents were prepared, extruded and molded in the same manner as in Example XXIV.
- the results of impact and flexural tests performed on the resultant molded parts are set forth in Table II.
- Base 60 Parts by Weight Po1y(BPA Carbonate) 8 , 20 Parts by Weight Chopped Glass Fibers and 20 Parts by Weight Glass Beads -
- Example XXXI - Control A blend of 70 parts by weight of bisphenol-A polycarbonate and 30 parts by weight of glass beads was prepared, extruded and molded into sample parts in the same manner as in Example I. The results of impact and flexural tests performed on the re- sultant molded parts are set forth in Table III.
