Title
(EN) RESIN COMPOSITION AND MOLDED BODY FORMED THEREFROM
(ZH) 树脂组合物、由该组合物形成的成型体
Abstract
(EN)
The purpose of the present invention is to provide: a novel vinyl chloride resin composition having exceptional transparency; and a molded article, in particular, a pipe joint, formed from said resincomposition. This resin composition comprises 3-15 parts by mass of a rubbery impact-absorbing material (B) for which the glass transition point (Tg) in differential scanning calorimetry (DSC) does not exceed 0 DEG C, and 0.1-10 parts by mass of a lubricant (C) that satisfies (i)-(iv) below, the content amounts above being indicated relative to 100 parts by mass of a vinyl chloride resin (A) having a chlorine content of 55-75 mass%. (i) The melt viscosity at 200 DEG C is 5-5,000 Mp*s (ii) The softening point is in the range of 60-180 DEG C (iii) The glass transition point (Tg) as measured in DSC is in the range of 0-100 DEG C (iv) A structural unit derived from at least one species selected from the group consisting of styrene, alpha-methylstyrene, indene, vinyl toluene, and isopropenyl toluene is contained in the molecule in an amount of 50-100 mass%
