Problems solved by technology

However, in recent years, people have further demanded a lower baking temperature in the aqueous dispersion. For example, when the baking temperature is lowered to 60°C and lower, the above-mentioned technology may not be able to obtain satisfactory results.

Embodiment 1-1～1-3

[0124] [Examples 1-1 to 1-3] (solvent system)

[0125] 500 g of a propylene-based random copolymer (Tm = 80° C., melt viscosity at 170° C.: about 3000 mPa·s) prepared using a metallocene catalyst as a polymerization catalyst was charged into a reaction kettle with an enamel lining. Add 5L chloroform, at 2kg / cm 2 Chlorination is carried out by feeding gaseous chlorine from the bottom of the reactor while irradiating ultraviolet rays under high pressure. In order to adjust the chlorine content, samples were taken on the way, and the solvent chloroform was distilled off with an evaporator. Then replace it with toluene / cyclohexane=70 / 30 (weight ratio), and add 2.0% by weight of epoxy resin (Epikote) 828 (manufactured by Yuhua Shieluepokishi Co., Ltd.) with respect to the resin as a stabilizer, so that the resin concentration is 20% by weight to obtain the chlorinated propylene-based random copolymer resin solutions of Examples 1-1 to 1-3 in which the chlorine content was changed...

Embodiment 2-1-2-3

[0126] [Example 2-1-2-3] (solvent system)

[0127] 700 g of a propylene-based random copolymer prepared using a metallocene catalyst as a polymerization catalyst (melt viscosity at Tm = 80° C., 170° C. is about 3000 mPa·s), 20 g of maleic anhydride, and 15 g of dicumyl peroxide were thoroughly mixed in advance. , feed the twin-screw extruder of L / D=34, φ=40mm, and the residence time is 10 minutes. The barrel temperature is set at 180°C (the first barrel - the seventh barrel) for reaction, and the exhaust is carried out in the seventh barrel to remove unreacted maleic anhydride to obtain maleic anhydride modified propylene random copolymerization things. 500 g of this resin was charged into a reaction vessel with an enamel lining, and chlorination was carried out in the same manner as in Example 1 to prepare a resin composition to obtain chlorine in Examples 2-1 to 2-3 whose chlorine content was changed as shown in Table 1. Propylene-based random copolymer resin solution.

Embodiment 3

[0129] 700g of propylene-based random copolymer (melt viscosity at Tm=92°C, 170°C is about 4100mPa·s) prepared with metallocene catalyst as polymerization catalyst and 15g of dicumyl peroxide were fully mixed in advance, and supplied to L / D =34, φ=40mm twin-screw extruder, the residence time is 15 minutes. The barrel temperature was set at 180° C. (the first barrel to the seventh barrel), and the molecular weight and molecular weight distribution were adjusted through thermal degradation to obtain a propylene-based random copolymer. 500 g of this resin was placed in an enamel-lined reactor, and chlorination was carried out in the same manner as in Example 1. After chlorination, a resin composition was prepared using ethyl acetate as a solvent instead of toluene, and the chlorinated propylene-based random copolymer resin solutions of Examples 3-1 to 3-3 whose chlorine content varied as shown in Table 1 were obtained.

Abstract

A novel binder resin which attains good adhesion to various substrates such as polyolefin resins, vinyl chloride resins, polycarbonate resins, polyethylene terephthalate resins, acrylonitrile / butadiene / styrene resins, and nylon resins even by low-temperature baking and is excellent in solvent solubility. Namely, a chlorinated propylene random copolymer produced by subjecting a propylene random copolymer which is obtained by copolymerizing propylene with other alpha-olefin by using a metallocene catalyst as the polymerization catalyst and which has a melting point (Tm) of less than 115 DEG C as determined with a differential scanning calorimeter (DSC) to degradation by heat preferably at a temperature ranging from the melting point of the copolymer to 350 DEG C and chlorination successively.

Description

technical field [0001] The present invention relates to chlorinated propylene-based random copolymers and compositions containing the same, more specifically, the present invention relates to polyolefin-based, vinyl chloride-based, polycarbonate-based, PET-based, ABS-based, nylon Copolymers with excellent adhesiveness or other excellent physical properties for sheets or films or molded articles suitable for cosmetics, paints, printing inks, adhesives, primers or adhesives, etc., and compositions containing these copolymers . Background technique [0002] Plastic has many advantages such as light weight, rust resistance, and a large degree of design freedom. Therefore, in recent years, it has been widely used as a material for automobile parts, electrical parts, and construction materials. In particular, polyolefin-based resins have many excellent properties such as low price, moldability, chemical resistance, heat resistance, water resistance, and good electrical properties...
