Samples	Stress at 300% Elongation/MPa	Tensile Strength/MPa	Elongation at break/%	Permanent Set/%	Shore A Hardness/∘	Tear Strength/KN/m
Neat SBR	1.4	1.5	327	0	46	7
PS(10)/SBR	1.9	10.7	581	10	58	16
PS(20)/SBR	2.2	14.5	623	16	65	22
PS(30)/SBR	2.3	17.6	652	18	72	28
PS(40)/SBR	2.4	18.0	649	24	77	31
PS(50)/SBR	2.6	17.7	644	26	82	36

Note that All samples were cured with 4 phr benzyl peroxide (BPO) at 95^∘C for 120 minutes.
