Title:
THERMOPLASTIC RESIN PROCESSING AID, AND THERMOPLASTIC RESIN COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2012/036173
Kind Code:
A1
Abstract:
[Problem] To provide a thermoplastic resin processing aid that can effectively increase molding/processing properties of a thermoplastic resin or a composition containing same without detracting from the intrinsic properties of the thermoplastic resin. [Solution] The processing aid for being combined with a thermoplastic resin is characterized by (1) the processing aid containing a copolymer (A) obtained by copolymerizing a) 50-95 wt% of an aromatic vinyl monomer, b) 5-50 wt% of a vinyl cyanide monomer, and d) 0-45 wt% of another vinyl monomer that can copolymerize with the aromatic vinyl monomer and the vinyl cyanide monomer (however, the total of the monomers used in the copolymer (A) is 100 wt%), (2) the peak molecular weight (Mp) of the copolymer (A) being at least one million, and (3) the copolymer being a particulate, wherein 1-50 wt% of particles with a particle size of at least 355 µm are contained in every 100 wt% of the copolymer (A).
