    • The present invention relates to an impact strength modifier for thermoplastic polyester resin and a thermoplastic polyester resin composition containing the same, more precisely an impact strength modifier for thermoplastic polyester resin prepared by graft-polymerization of a) 20-80 weight % of multilayered rubber latex in which the ratio of particle diameter (P b /P a ) of an inner layer (P a ) to outer layer is 1.05-1.5, and glass transition temperature of the inner layer or the outer layer is up to -30 °C; and b) 20-80 weight % of vinyl monomer. According to the present invention, a thermoplastic polyester resin composition having excellent transparency and improved impact strength can be provided by containing an impact strength modifier for thermoplastic polyester resin having multilayered structure in which content of rubber latex, glass transition temperature, particle diameter and refraction index are regulated.
    • 本发明涉及一种用于热塑性聚酯树脂的冲击强度改性剂和含有该改性剂的热塑性聚酯树脂组合物,更准确地说,涉及一种用于热塑性聚酯树脂的冲击强度改性剂, -80重量%的多层橡胶胶乳,其中内层(P sub-1)的粒径(P b / P a a) )为1.05-1.5,内层或外层的玻璃化转变温度高达-30℃; 和b)20-80重量%的乙烯基单体。 根据本发明,通过含有具有多层结构的热塑性聚酯树脂的冲击强度改性剂,可以提供具有优异的透明性和改善的冲击强度的热塑性聚酯树脂组合物,其中橡胶胶乳的含量,玻璃化转变温度,粒径和折射率 受到监管。
