Abstract
The present invention comprises material resin comprising polyamide or polyethylene-based resin; and polyacrylate copolymer obtained by absorption of acrylate monomer, polymerization initiator and functional monomer chosen from among acrylic acid, methacrylic acid, and a mixture of the acrylic acid and the methacrylic acid into the material resin and subsequent polymerization, providing polyacrylate-based polymer, where 128 to 955 parts by weight of the polyacrylate copolymer are used for every 100 parts by weight of the material resin.
Claims16
Polyacrylate-based polymer comprising:
- material resin comprising polyamide or polyethylene-based resin;
- and
- polyacrylate copolymer obtained by absorption of acrylate monomer, functional monomer chosen from acrylic acid, methacrylic acid and a mixture of the acrylic acid and the methacrylic acid, and polymerization initiator, into the material resin and subsequent polymerization,
- wherein 128 to 955 parts by weight of the polyacrylate copolymer is dispersed in every 100 parts by weight of the material resin.
Process for manufacturing a polyacrylate-based polymer, comprising:
- first-polymerization step of absorbing 50 to 200 parts by weight of acryl monomer and polymerization initiator into 100 parts by weight of material resin comprising polyamide or polyethylene-based resin dispersed in 500 to 1000 parts by weight of water, and first-polymerizing the monomers;
- and
- second-polymerization step of absorbing 50 to 200 parts by weight of acrylate monomer, 2 to 35 parts by weight of functional monomer chosen from among acrylic acid, methacrylic acid and a mixture of the acrylic acid and the methacrylic acid, and polymerization initiator, into 100 parts by weight of the products from the said first-polymerization, and second-polymerizing the monomers;
- wherein 0.2 to 2.5 mol % of the polymerization initiator is used for total sum of molecular numbers of the monomers and polymerization initiator in each of first and second polymerization.
