Embodiment

[0060] Next, the present invention will be described with reference to examples, but the present invention is not limited to these examples.

[0061] In this specification, % and parts represent % by weight and parts by weight unless otherwise specified.

[0062] However, in the present invention, extrusion moldability, stain resistance, water repellency, oil repellency, color development, friction resistance, water resistance, oil resistance, and adhesiveness were evaluated by the following methods.

[0063]

[0064] The mixture was kneaded using a single-screw extruder with a diameter of 20 mm (screw CR=3.0, 60 rpm), and extruded sheets (thickness: 1.5 mm) were produced by extrusion molding using a T-die die. The sheets were evaluated according to the following criteria.

[0065] ○: The shape of the edge portion and the smoothness of the surface are good

[0066] △: The shape of the edge portion and the smoothness of the surface are slightly inferior

[0067] X: The sha...

Synthetic example 1

[0109] In a polymerization vessel equipped with a stirrer, a thermometer and a nitrogen inlet, after nitrogen replacement, 2400 parts by weight of deionized water, 1164 parts by weight of vinyl chloride, 36 parts by weight of C 6 f 13 -(CH 2 ) 2 OCOC (CH 3 )=CH 2 (hereinafter referred to as "C6F13MA monomer"), 2 parts by weight of bis(2-ethylhexyl) peroxydicarbonate, 1 part by weight of partially saponified polyvinyl alcohol, 2 parts by weight of hydroxypropyl methylcellulose, while stirring While raising the temperature to 56°C, the polymerization reaction was started. When the polymerization internal pressure reached 0.1 MPa, the remaining pressure was released and cooled, washed three times with 1500 parts by weight of deionized water, filtered, and dried at 50°C to obtain a copolymer. The composition of the copolymer was 3.3 parts by weight of C6F13MA monomer per 100 parts by weight of vinyl chloride.

Synthetic example 2

[0111] A copolymer was synthesized in the same manner as in Synthesis Example 1 except that the C6F13MA monomer was 120 parts by weight and the vinyl chloride was 1080 parts by weight. The composition of the copolymer was 11.9 parts by weight of C6F13MA monomer per 100 parts by weight of vinyl chloride.

Abstract

Disclosed is a vinyl chloride polymer comprising 100 parts by weight of a constituent unit (A-1) derived from vinyl chloride and 1 to 20 parts by weight of a constituent unit (A-2) derived from a fluorinated acrylate ester. Also disclosed is a vinyl chloride resin composition comprising (A) 0.2 to 20 parts by weight of the vinyl chloride polymer and (B) 100 parts by weight of a vinyl chloride resin. The vinyl chloride polymer may additionally comprise 50 parts by weight or less of a constituent unit (A-3) derived from a saturated fatty acid vinyl ester. Furthermore, the vinyl chloride polymermay additionally comprise 30 parts by weight or less of a constituent unit (A-4) derived from a vinyl ester containing an active hydrogen group. It becomes possible to improve the water-repellent / oil-repellent properties of a vinyl chloride resin.

Description

technical field [0001] The present invention relates to a vinyl chloride polymer and a vinyl chloride resin composition comprising the vinyl chloride polymer and a vinyl chloride resin. The vinyl chloride polymer and the vinyl chloride resin composition are excellent in water and oil repellency. Background technique [0002] Vinyl chloride resin has excellent properties such as flame retardancy, mechanical properties, weather resistance, water resistance, and scratch resistance, and its flexibility can be adjusted in a wide range by adding a plasticizer. Therefore, it is used as a film, sheet, It is used in a wide range of applications such as miscellaneous goods, artificial leather, wire coverings, molded products such as wallpaper, building materials, and pipes, and base resins for inks and paints. [0003] However, vinyl chloride resins generally do not have sufficient water and oil repellency, and sometimes it is difficult to remove water or oil when used in the above-m...
