摘要：
Provided are a break-resistant copolymer having high transparency and heat resistance and also having a high tensile strain at break, and a molded article.A copolymer contains 80% by mass to 98% by mass of structural units derived from a methacrylic ester monomer and 2% to 10% by mass of ester structural units derived from a cyclic ketene acetal monomer. The copolymer has a weight average molecular weight of 80,000 or more and a molecular weight distribution of 1.75 to 3.80.
