Net income in the second quarter of 2021 increased by $ 507 million from second quarter 2020 net income of $ 15 million , or $ 0.11 per share , on net sales of $ 1,709 million . Income from operations for the second quarter of 2021 was a quarterly record of $ 720 million , and increased by $ 684 million from income from operations of $ 36 million for the second quarter of 2020. The increases in net income and income from operations were primarily driven by significantly higher sales prices and margins for most of our major products and higher sales volumes in our Vinyls Segment . The increase in sales prices for PVC resin were driven by the strong demand in North American residential construction and the repair and remodeling markets which also drove demand in our building and construction materials business . Additionally , polyethylene experienced robust strength from packaging and other consumer markets driving higher prices and margins resulting from the rebound in global economic activity following the onset of the COVID - 19 pandemic in the first half of 2020 . Second quarter 2021 net income of $ 522 million , or $ 4.04 per share , increased by $ 280 million from first quarter 2021 net income of $ 242 million , or $ 1.87 per share . Income from operations of $ 720 million for the second quarter of 2021 increased by $ 374 million from income from operations of $ 346 million for the first quarter of 2021. The increases in net income and income from operations versus the prior quarter were primarily due to higher sales prices and higher margins for all of our major products including PVC resin , polyethylene , caustic soda and our building and construction materials as well as higher sales volumes for PVC resin as operations rebounded following the impacts of the Winter Storm Uri in the first quarter . The increases in sales prices and volumes for our products contributed to higher margins and strong earnings in our building and construction materials business . For the first six months of 2021 , net income of $ 764 million , or $ 5.91 per share , increased by $ 604 million from the first six months of 2020 net income of $ 160 million , or $ 1.24 per share . Income from operations of $ 1,066 million for the first six months of 2021 increased by $ 894 million from income from operations of $ 172 million for the first six months of 2020 , which was severely impacted by the onset of the global COVID - 19 pandemic . The increases in net income and income from operations were primarily due to the global economic recovery , which has driven strong demand and higher sales prices and margins for most of our major products . These increases were partially offset by the impacts to production and sales volumes as a result of Winter Storm Uri in the first quarter of 2021 . On June 20 , 2021 , Westlake announced that it had entered into a definitive agreement with Boral Industries Inc. , a wholly owned subsidiary of Boral Limited , under which Westlake will acquire Boral's North American building products businesses in roofing ; siding , trim and shutters ; decorative stone ; and windows ( " Boral North America " ) . The combination of these businesses with Westlake's leading building products businesses creates a stronger business with significantly increased scale and complementary product offerings , and enhanced growth prospects throughout the North American building products market . i
