Definitions
- This invention relates to flame retardant, aromatic polycarbonate resins having improved impact strength at low melt viscosities.
- Polycarbonate polymers are known as being excellent molding materials since products made therefrom exhibit such properties as high impact strength, toughness, high transparency, wide temperature limits (high impact resistance below -60o C and a UL thermal endurance rating of 115o C with impact), good dimensional stability, good creep resistance, good flame retardance, and the like.
- these properties are generally exhibited in polycarbonate resins having relatively high melt viscosities such as on the order of about 2400 poises. It would be desirable to add to this list of properties that of improved impact strength when the polycarbonates have relatively low melt viscosities such as on the order of about 1500- 2000 poises.
- These low melt viscosity polycarbonate resins having improved impact strength can then be employed to form molded articles requiring long thin wall s ections which are difficult to mold when polycarbonates having high viscosities are employed.
- any of the aromatic polycarbonates can be employed that are prepared by reacting a diphenol with a carbonate precursor.
- Typical of some of the diphenols that can be employed are bisphenol-A (2, 2-bis(4-hydroxyphenyl)propane), bis (4-hydroxyphenyl) methane, 2, 2-bis(4-hydroxy- 3-methylphenyl)propane, 4, 4-bis(4-hydroxyphenyl)heptane, 2, 2- (3, 5, 3',5'-tetrachloro-4, 4'-dihydroxydiphenyl)propane, 2, 2-(3, 5 3', 5'-tetrabromo-4, 4'-dihydroxydiphenyl)propane, (3, 3'-dichloro- 4, 4' -dihydroxyphenyl)methane.
- Other diphenols of the bisphenol type can also be used such as are disclosed in U. S. Patents 2, 999, 835, 3, 028, 365, and 3, 334, 154.
- diphenols can then be employed to obtain the high molecular weight aromatic polycarbonates of the invention which can be linear or branched homopolymers or copolymers as well as mixtures thereof or polymeric blends and which generally have an intrinsic viscosity (IV) of about 0. 40-1, 0 dl/g as measured in methylene chloride at 25o C.
- IV intrinsic viscosity

- the rubbery acrylic-butadiene copolymers that can be employed are those which are commercially available such as those offered by Rohm and Haas Company under their product identifications KM-228, KM-607 and KM-611.
- the rubbery copolymer can be blended with the low melt viscosity polycarbonate in amounts of about 0. 5 to 10%, preferably 1 to 5% and optimumly 2 to 4% based upon the weight of the polycarbonate.
- EXAMPLE I One hundred (100 )parts of an aromatic polycarbonate, prepared by reacting 2, 2-bis(4-hydroxyphenyl)propane and phos gene in the presence of an acid acceptor and a molecular weight regulator and having a melt viscosity of about 1650 poises was mixed with 4. 3 parts of each of two rubbery acrylicbutadiene copolymers by tumbling the ingredients together in a laboratory tumbler. The resulting mixture was then fed through an extruder which was operated at about 265o C and the extruder was comminuted into pellets.
- the pellets were than injection molded about 315°C into test bars of about (5 in.) 12.7 cm by 1/2 in.) 1.27 cm by about (1/16-1/8 in.) 0.16-0.32 cm thick and into test squares of about (2 in. by 2 in.) 5 cm x 5 cm by about (1/8 in.) 0.32 cm thick.
- the test bars (5 for each test listed in the Tables) were subject to the notched Izod impact test in accordance with ASTM D-256 on test bars as molded and after the test bars had been subjected to accelerated heat aging at 125°C for periods set forth in Table 1 below wherein the acrylic-butadiene copolymers are those obtained from Rohm and Haas Company and are shown by their product identifications.
- the unmodified polycarbonate at this low melt viscosity lost its ductile impact strength in less than one hour.
- the formulation containing KM-607 retained its ductile impact strength up to about 8 hours at 125°C whereas the formulation containing KM-611 retained its ductile impact strength after being heat aged at 125°C for over 16 hours.
- Example i The procedure of Example i was repeated except that the polycarbonate obtained had a melt viscosity of 1970 poises. This polycarbonate was also formulated with the acrylic-butadiene copolymers as in Example 1 and subjected to the same tests. The results obtained are set forth in Table II.
- An aromatic polycarbonate was prepared by reacting 2,2-bis (4-hydroxyphenyl) propane and phosgene in the presence of an acid acceptor and a molecular weight regulator to obtain a polycarbonate having a melt viscosity of about 4000 poises.
- a copolycarbonate was also prepared by reacting 2,2-bis (4-hydroxyphenyl) propane and 2,2-bis (4-hydroxy-3,5-dibromophenyl) propane and phosgene the presence of an acid acceptor and a molecular
- V-0 Average flame and/or glowing after removal of the igniting flame shall not exceed 5 seconds and none of the specimens shall drip flaming particles which ignite absorbent cotton.
- V-I Average flaming and/or glowing after removal of the igniting flame shall not exceed 25 seconds and the flowing does not travel vertically for more than ( 1 /8") 0. 32 cm of the specimen after flaming ceases and glowing is incapable of igniting absorbent cotton.
- V-II Average flame and/or glowing after removal of the igniting flame shall not exceed 25 seconds and the specimens drip flaming particles which ignite absorbent cotton.
- a test bar which continues to burn for more than 25 seconds after removal of the igniting flame is classified, not by UL-94, but by the standards of the instant invention as "burns”. 0 The results of these tests are shown in Table III,
- Example 4 The procedure of Example 3 was repeated except that the polycarbonate obtained had a melt viscosity of 1900 poises, the amount of titanium dioxide pigment added was increased to 2.5% and the KM-611 acrylic-butadiene copolymer level was increased to 6%. The same tests were run as in Example 3, the results of which are shown in Table IV.
