摘要:
A process for producing a polyolefin-based resin composition, which comprises melt-kneading 100 pans by weight of a polyolefin-based resin and not less than 0.05 parts by weight to less than 2 parts by weight of polymer fine particles comprising 0.10 to 90% by weight of a volatile component as an anti-blocking agent.

A polypropylene resin composition which comprises:
(a) 100 parts by weight of a crystalline polypropylene resin, and (b) 0.05 or more but less than 1 part by weight of crosslinked polymer beads which have a weight average particle diameter of 0.5-5 µm and which comprise 60-96% by weight of styrenic monomer units, 2-38% by weight of radical-polymerizable monomer units, the refractive index of the polymer of the radical-polymerizable monomer being 1.50 or less, and 2-50% by weight of crosslinkable monomer units; may be oriented in at least a uniaxial direction to give an oriented film having an average protuberance height of 60-600 nm on its surface and possessing good transparency, slip and blocking resistance characteristics.
摘要:
A polyolefin resin composition comprising: (a) 100 parts by weight of a polyolefin resin; and (b) 0.05 to 1 part by weight of beads of a crosslinked polymer comprising (1) 5 to 99% by weight of a radically polymerizable monomer unit of formula (A): wherein R 1 is hydrogen or a hydrocarbon group having 1 to 5 carbon atoms and R 2 is a hydrocarbon group having 5 to 30 carbon atoms, (2) 0 to 94% by weight of a radically polymerizable monomer unit other than the monomer unit of formula (A), and (3) 1 to 20% by weight of a crosslinkable monomer unit, the percentages being measured relative to the total weight of components (1), (2) and (3), said crosslinked polymer beads having a critical surface tension of 40 dyne/cm or less.
摘要:
An antiblocking agent master batch which comprises 100 parts by weight of a polyolefin resin and 1 - 50 parts by weight of crosslinked polymer beads may be mixed with a polyolefin resin to give a composition in which the content of crosslinked polymer beads is 0.05 or more but less than 1 part by weight per 100 parts by weight of the total polyolefin resin. This composition may be oriented in at least a uniaxial direction to give an oriented film having good transparency.
