RESIN COMPOSITION AND MOLDED BODY FORMED THEREFROM

Document Type and Number:

WIPO Patent Application WO/2018/143002

Kind Code:

A1

Abstract:

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 resin composition. 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°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°C is 5-5,000 mP·s (ii) The softening point is in the range of 60-180°C (iii) The glass transition point (Tg) as measured in DSC is in the range of 0-100°C (iv) A structural unit derived from at least one species selected from the group consisting of styrene, α-methylstyrene, indene, vinyl toluene, and isopropenyl toluene is contained in the molecule in an amount of 50-100 mass%
