The present invention relates to a chlorine-containing resin composition with improved appearance, light resistance, and impact resistance. Conventional polyvinyl chloride, acrylonitrile, butadiene, styrene resin, methyl methacrylate,
Attempts have been made to increase impact resistance by blending impact reinforcement agents such as butadiene-styrene resin, vinyl acetate-ethylene copolymer, and chlorinated polyethylene. On the other hand, a sulfur-containing organotin stabilizer and a malate-based organotin stabilizer are added for the purpose of thermally stabilizing polyvinyl chloride blended with an impact strengthener. However, these polyvinyl chloride compositions have poor dispersibility among the polyvinyl chloride, impact strengtheners, and stabilizers, so during processing, moldability (lubricity) and extrusion workability decrease, resulting in poor appearance. However, it is not possible to impart sufficient impact strength to the processed product, and the impact strength gradually decreases when the product is exposed outdoors for a long period of time. Recently, building materials such as window frames, decking materials,
It has been applied to rain gutters, exterior wall materials, etc., and there is a strong desire to develop polyvinyl chloride with particularly good appearance, light resistance, and impact resistance. As a result of research from the above viewpoint, the present inventors have found that by using an acrylic copolymer that does not contain butadiene as an impact strengthener and an alkyl ester organotin compound having a specific number of carbon atoms as a stabilizer, the processability and light resistance can be improved. We have succeeded in obtaining a chlorine-containing resin composition that has improved properties, as well as excellent impact resistance and appearance. That is, in the present invention, for 100 parts by weight of a chlorine-containing resin, (a) 1 to 20 parts by weight of an acrylic copolymer not containing butadiene as an impact strengthener and (b) a stabilizer of the general formula [] , [] and [] R〓Sn〔S(CH 2 )nCOOR 2 〕 2 [〕] R〓Sn〔OOCCH＝CHCOOR 2 〕 2 〔〕 R 1 Sn〔OOCCH＝CHCOOR 2 〕 3 〔〕 [in the formula R 1 is an alkyl group having 1 to 12 carbon atoms, a group -
CH 2 CH 2 COOR 3 (where R 3 represents an alkyl group or alkenyl group having 1 to 8 carbon atoms), R 2 represents an alkyl group or alkenyl group having 10 to 20 carbon atoms, and n is 1
This is a chlorine-containing resin composition characterized in that 0.1 to 10 parts by weight of one or more organic tin compounds represented by the following formula (indicating an integer of 2 to 2) are added to the copolymer. In the present invention, the butadiene-free acrylic copolymer used in the impact strength agent is at least one monomer constituent unit selected from acrylonitrile, methacrylic ester, and acrylic ester. This means that the molecule contains an acrylic compound. however,
The copolymer shall not contain any butadiene structural units. Examples of such acrylic copolymers that do not contain butadiene include acrylonitrile/chlorinated polyethylene/styrene copolymer, styrene/acrylonitrile copolymer, acrylic rubber/acrylonitrile/styrene copolymer, and acrylic rubber/methyl methacrylate.・Acrylonitrile copolymer, methyl methacrylate ・ethyl acrylate ・

In addition, the alkyl group in R 2 may include, for example, carbon number 10-12 (C 10-12 ), carbon number
12-14 ( C12-14 ), carbon number 12-18 ( C12-18 ), carbon number 16-18 ( C16-18 ) mixed alcohol, commercially available under the name "Diadol", e.g. Mixed alkyl groups derived from branched synthetic alcohols having 18 carbon atoms (C 18 ), such as those commercially available under the names of mixed alcohols having 11 to 15 carbon atoms (C 11-15 ) and “Diadol” and “Oxocol”. and branched alkyl groups. These stabilizers can be used alone or in combination of two or more. That is, in the organotin compounds represented by the above general formulas [], [] and [],
The compounds [], [] or [] are each alone, and the compounds [] and [], [] and [], [] and [] and [] and [] and [] are 2.
It can be added as a species or as a combination of three species. In the present invention, the amount of impact strengthener and stabilizer added is 1 to 1, respectively, per 100 parts by weight of chlorine-containing resin.
20 parts by weight, 0.1 to 10 parts by weight. impact toughener
If it exceeds 20 parts by weight, it will affect the physical properties of the chlorine-containing resin, such as the softening point, and is not practical. Moreover, if it is less than 1 part by weight, sufficient impact strength cannot be imparted. The impact toughener of the present invention does not contain any butadiene structural units in the acrylic copolymer. When the butadiene structural unit is present, a certain degree of impact strength can be obtained in the product, but there is a drawback that the light resistance is poor and the impact strength is extremely reduced over time. Examples of the chlorine-containing resin of the present invention include vinyl chloride resin, vinylidene chloride resin, vinyl chloride, vinyl acetate, vinyl propionate, vinyl butyrate, vinylidene chloride, styrene, ethylene, propylene, methyl methacrylate, dialkyl fumarate, or malate. Mention may be made of copolymers, such as those formed by polymerization with one or more comonomers such as analogs. The chlorine-containing resin composition of the present invention can be used together with a chlorine-containing resin, an impact strengthener, a stabilizer, and optionally other additives such as a lubricant, an antioxidant, a pigment, a coloring agent, and a filler in a Banbury mixer, a mixing roll, a calender, etc. Blending can be carried out by a conventional method such as using a roll or an extruder. The chlorine-containing resin composition of the present invention thus obtained can be easily processed by conventional methods such as various molding methods such as injection molding, blow molding, vacuum molding, blow molding, extrusion molding, and injection blow molding. It will be done.
The resulting molded products are widely used as building materials, pipes, sheets, and various parts. Since the chlorine-containing resin composition of the present invention has good mutual dispersibility among its constituent components, it has excellent moldability (lubricity) and extrusion workability during processing, and has excellent appearance, light resistance, and impact resistance after processing. A molded product is obtained.
Therefore, the molded product obtained by the present invention is particularly suitable for use in building materials that require light resistance and impact resistance, such as window frames, decking materials, rain gutters, and exterior wall materials. Next, the present invention will be explained with reference to Examples. In addition,
