Acrylonitrile-Styrene-Acrylate Particles with Different Microstructure for Improving the Toughness of Poly(styrene-co-acrylonitrile) Resin

Table 3

Glass transition temperature of ASA particles with different shell compositions.

Sample	Shell composition^a
ASA-R1	4 : 1	-43.9	111.6
ASA-R2	3 : 1	-42.5	112.6
ASA-R3	2 : 1	-42.1	117.0
ASA-R4	1 : 1	-40.9	117.7

^aBased on shell monomer weight ratio (St : AN). ^b, ^c, the glass transition temperature in low- and high-temperature regions is measured by DSC Q2000.
