Title: Thermoplastic resin film
Inventor: HASEGAWA JUN
IPC: C08F2/08
Filed: 1990-09-04
Abstract: PURPOSE:To provide a thermoplastic resin film having improved traveling property, abrasion resistance and strength by compounding crosslinked polymer particles which are prepared by a specific polymerization method and have a specified particle diameter and a particle diameter variance. CONSTITUTION:A hydrophobic monomer (e.g. styrene) and polymethacrylic acid in an amount of 1-40wt.% based on the monomer are subjected to polymerization reaction up to a conversion efficiency to polymer of >=30% in a solvent which dissolves the hydrophobic monomer and the polymethacrylic acid but does not dissolve the polymer from the hydrophobic monomer (e.g. methyl alcohol) in the presence of a radical polymerization initiator soluble in the above solvent. Then, a multi-functional ethylenic monomer (e.g. divinyl benzene) soluble in the solvent is added to the polymerization system and the polymerization is continued to prepare a crosslinked polymer having a particle diameter of 0.1-20mum and a particle diameter variance of <=1.2. The thus prepared crosslinked polymer particles are added to a thermoplastic resin in the range of 0.01-10wt.%, preferably at the time of producing the resin, followed by processing the polymer composition into a thermoplastic resin film.
