摘要:
A stretched film comprised of a “B1” layer comprised of a thermoplastic resin 1, an “A” layer comprised of a styrene-based resin, and a “B2” layer comprised of a thermoplastic resin 2 stacked in that order and having a width of over 1000 mm, wherein a ratio of the “A” layer in the stretched film is 45 wt % or less, an average value of an orientation angle θ with respect to a width direction across at least 1000 mm of the width direction is 0°±1°, a variation in orientation angle θ is 0.5° or less, and a value of an Nz coefficient is −3.5 to −0.5 in range.

摘要:
Granules of a polyvinyl chloride resin for preparation of paste which comprise 10% by weight or less of components having diameters of 10 &mgr;m or smaller and less than 0.5% by weight of over size components after classification using a 149 &mgr;m standard sieve, have a bulk density of 0.45 to 0.58 g/cm3 and give a plastisol comprising less than 0.3% by weight of over size components after classification using a 62 &mgr;m standard sieve, wherein the plastisol is obtained by mixing 100 g of the granules of a polyvinyl chloride resin and 50 g of dioctyl phthalate; and a process for producing granules of a polyvinyl chloride resin for preparation of paste which comprises spray-drying an aqueous dispersion of a vinyl chloride polymer obtained by emulsion polymerization or micro suspension polymerization of vinyl chloride or a mixture containing vinyl chloride and a monomer copolymerizable with vinyl chloride, classifying granular particles obtained by the spray-drying using ultrasonic vibration sieves which are equipped with a screen having an opening of 149 &mgr;m or smaller and removing the over size components.
