Vidare har de egenarten att vara kompatibla både med polystyren eller slagbe- ständig polystyren såväl som med ABS-termopolymerer och styren/akrylonitrilsampolymerer (SAN). W Icke desto mindre uppvisar dessa arylaromatiska polymerer, modifierade med en eteniskt omättad nitril, såsom i allmänhet alla vinylaromatiska polymerer, den nackdelen att de har en låg värmedistorsionstemperatur, så att deras värmebeständighet inte blir helt tillfreds- ställande för att uppfylla kraven inom några tillämp- ningsomràden, såsom t ex bilsektorn. Ändamålet med föreliggande uppfinning är att för- bättra värmebeständigheten hos de vinylaromatiska poly- merer som är modifierade med en eteniskt omättad nitril, utan att försämra och företrädesvis förbättra deras utmärkta kemisk-fysikaliska egenskaper.They can also be easily manufactured using other machining techniques currently in use. Furthermore, they have the peculiarity of being compatible with both polystyrene or impact-resistant polystyrene as well as with ABS thermopolymers and styrene / acrylonitrile copolymers (SAN).

Egenskaperna hos blandningarna enligt uppfinningen har testats på teststycken formade genom strängsprut- ning, med användning av följande metoder: l. Värmedistortionstemperaturen (HDT) har bestämts en- ligt standarden ASTM D 648, vid 4,64 kp/cmz (66 psi) och vid 18,5 xp/cmz (264 psi). 2. Vicat-mjukningspunkt förfarande A har bestämts enligt standard ASTM D 1525. 3. IZOD-slaghàllfastheten har bestämts vid 23°C enligt standarden ASTM D 256 med användning av teststycken som var 1,27 x 0,32 cm (l/2" x l/8"). 4. Testen avseende beständigheten mot freon(35C) här genomförts pá testbitar som utsatts för krypning i drag- test, varvid deras centrala del, för en 40 mm sträck- ning, hållits i kontakt med flytande freon ll. För detta ändamål fixerades en glasbehàllare innehållande freon ll med hjälp av en gummipackning vid den nedre änden av 10 15 20 25 455 199 7 det vertikalt anordnade teststycket i motsvarighet till dess vidare sträckning. Teststycket utsattes för en belastning av 100 kp/cmz och tiden som erfordrades för brott därav mättes.The properties of the mixtures according to the invention have been tested on test pieces formed by extrusion, using the following methods: 1. The heat distortion temperature (HDT) has been determined according to the standard ASTM D 648, at 4.64 kp / cm 2 (66 psi) and at 18.5 xp / cm 2 (264 psi). 2. Vicat softening point method A has been determined according to standard ASTM D 1525. 3. The IZOD impact strength has been determined at 23 ° C according to standard ASTM D 256 using test pieces that were 1.27 x 0.32 cm (1/2 " xl / 8 "). The test for resistance to freon (35C) was carried out here on test pieces which had been subjected to creep in tensile tests, their central part, for a 40 mm distance, being kept in contact with liquid freon ll. For this purpose, a glass container containing freon was fixed by means of a rubber gasket at the lower end of the vertically arranged test piece corresponding to its further extension. The test piece was subjected to a load of 100 kp / cm 2 and the time required for breaking it was measured.
EXEMPEL 1-4 Med hjälp av en enkelskruvssträngsprutningsanordning BANDERA TR 45 som har ett förhållande längd/diameter av 30 strängsprutades med avgasning och vid den tempe- ratur som anges i tabell I blandningar bestående av: - en modifierad vinylaromatisk polymer med följande sammansättning: 72 viktš styren, 12 vikt% alfa-metyl- -styren, 8 vikt% akrylonitril och 8 vikt% gummi; - ett aromatiskt polykarbonat liknande “SINVET 221", sålt av ANIC från S. Donato Milanese - Milano, i de i tabell I angivna mängderna; och - 0,05 vikt% av ett steriskt hindrat fenoliskt antioxi- dationsmedel såsom "IRGANOX 1076".EXAMPLES 1-4 Using a single screw extruder BANDERA TR 45 having a length / diameter ratio of 30 was extruded by degassing and at the temperature given in Table I mixtures consisting of: - a modified vinyl aromatic polymer having the following composition: 72 wt. styrene, 12% by weight of alpha-methyl-styrene, 8% by weight of acrylonitrile and 8% by weight of rubber; an aromatic polycarbonate similar to "SINVET 221", sold by ANIC from S. Donato Milanese - Milano, in the quantities indicated in Table I, and - 0,05% by weight of a sterically hindered phenolic antioxidant such as "IRGANOX 1076".
Genom att skära filamenten som kom från sträng~ sprutningsanordningen erhölls granuler som torkades vid 90°C i 2 h. Granulerna formades genom formsprutning vid en temperatur som var 20°C högre än den lägsta fyll- ningstemperaturen för formrummet på en NEGRI & BOSSI - 17 - 110 FA-press och sålunda erhölls teststycken.By cutting the filaments coming from the extruder, granules were obtained which were dried at 90 ° C for 2 hours. The granules were formed by injection molding at a temperature which was 20 ° C higher than the lowest filling temperature for the mold space on a NEGRI & BOSSI - 17 - 110 FA presses and thus test pieces were obtained.
