In Formula (1), n is an integer of 3 to 6, each Y and Z are independently selected from o-vinylphenoxy group and phenoxy group, and each Y and Z are not phenoxy group at the same time. The prepolymer is prepared by subjecting a mixture to a prepolymerization reaction, and the mixture at least comprises the component (A) and the component (B). An article is made from the resin composition. The article includes a prepreg, a resin film, a laminate or a printed circuit board and achieves improvements in one or more properties including resin filling uniformity, dissipation factor variation rate under heat, glass transition temperature, Z-axis ratio of thermal expansion, peeling strength and thermal resistance after moisture absorption.
