selection types different content ABS:

ABS16（16%Rubber）, ABS38（38%Rubber）, ABS45（45%Rubber） and ABS50（50%Rubber）进行 evaluation. generally, ABS impact strong/high degree 会随 胶 content upper rise improve/increase, to 一定程 degree （45%） rear improves again obvious, 如图1, can to ABS for thick degree property ratio PC low more, its 1/4” impact can 达1/8” impact 50% above （PC has 20%-25%）.

图 table/sheet 1 ABS胶 amount for ABS impact strong/high degree effect/influence

will above different amount ABS and PC3.2 （Mw=3.2w） blending rear made formed alloy, its impact property can temperature degree 变化如图2.

图2. different amount ABS for PC/ABS in different temperature degree lower impact strong/high degree effect/influence

can 看出, in normal temperature （25℃）时, different amount ABS PC/ABS均 performance high tough property, impact in 700-750J/m. temperature degree reduce, amount relatively low PC/ABS缺口 impact fast speed decline, in -30℃时, PC/ABS16 缺口 impact decline to 220J/m, 而PC/ABS38 and PC/ABS45 still maintain 650J/m above. need attention/notes is, ABS50 in and PC blending 时, formed PC heavy degradation, method made has alloy （ rear has 讨论）.

will ABS38 and combined SAN复配 made different content （0%-38%） emulsion method ABS, again separation and PC3.2 blending made alloy, its content for PC/ABS脆 tough temperature degree and impact strong/high degree effect/influence, 如图3 and 图4. 由图3, ABS胶 content high 于10%时, PC/ABS tough temperature degree 随 胶 content rise high 而逐渐 reduce; 而ABS胶 content low 于10%时, tough temperature degree amount decrease/reduce 而迅猛 improves. for/regarding requirements low temperature tough property PC/ABS 说, maintain ABS in content in value above is necessary.

图3.ABS胶 content for PC/ABS脆 tough temperature degree effect/influence

图4.ABS胶 content for PC/ABS notched impact strength effect/influence

图4 table/sheet 明ABS content in value, make PC/ABS in different conditions lower 发生脆 tough 转变, amount to amount rear, its notched impact strength again amount increase obvious improves. for/regarding 3.18mm strip/profile 说, ABS胶 content to 5%即 can make PC/ABS performance tough property, for/regarding 6.35mm样 strip/profile 说, content need to 10% above performance tough property.

but also, 6.35mm strip/profile in amount is 10% 时, gate and gate fracture performance different. gate performance tough property, and 断面周围 has obvious force phenomenon, gate performance tough property, 且断面呈脆 property fracture. this type of phenomenon main/primary and ABS in PC in versus has 关, 包括橡胶 versus large small, 形状, dispersion and other 情况（ rear has 讨论）.

can 见, in PC in 引入ABS rear, can reduce PC for thick degree and impact property. generally, ABS胶 amount in 一 临界 value, make for PC/ABS in normal temperature 时呈现脆 tough 转变, in upper, PC/ABS缺口 impact again amount increase obvious improves; also in 一 临界 value, make PC/ABS tough temperature degree 呈现突变, ultra- 此临界 value 时, tough temperature degree 随 胶 content improves 而不断 reduce. ABS in PC in versus 态也会 for PC/ABS tough property generate important effect/influence.
