Abstract

The invention discloses a polyolefin and polyvinyl chloride functional modifier and relates to the field of thermoplastic modified additives for compatibility and copolymerization of polyolefin and polyvinyl chloride. At present, the modifier does not exist in China. The modifier is a high molecular polymer which is polymerized by the following raw materials in parts by weight in a reaction kettle: 35-40 parts of styrene, 2-6 parts of maleic anhydride, 3-5 parts of maleic acid and 60-65 parts of vinyl chloride. The preparation method is as follows: the raw materials in certain parts by weightare put into a reaction kettle, stirred uniformly and heated up to 45-65 DEG C, reacting for 2-3 hours, thus obtaining the polyolefin and polyvinyl chloride functional modifier. As a thermoplastic modified additive for the compatibility and copolymerization of the polyolefin and the polyvinyl chloride, when the polyolefin and the polyvinyl chloride are polymerized, the compatibility and copolymerization of the polyolefin and the polyvinyl chloride can be realized by adding the functional modifier, and the plastic rubber of a new variety formed by the polymerization has high quality, excellentheat resistance, excellent fire resistance and excellent plasticizing processing property.

Description

technical field [0001] The invention relates to the field of thermoplastic modification additives for compatible copolymerization of polyolefin and polyvinyl chloride, in particular to a functional modifier for compatible copolymerization of polyolefin and polyvinyl chloride. Background technique [0002] With the rapid development of society, various industries have more and more requirements for plastic varieties, and the requirements for plastic quality are getting higher and higher. In order to meet the needs of social development, professional technicians in the plastics industry study the polymerization of polyolefins (such as polyethylene, polypropylene, etc.) and polyvinyl chloride to produce new plastic varieties. However, polyolefin is incompatible with polyvinyl chloride, and the polymerization is difficult, so it is impossible to polymerize polyolefin and polyvinyl chloride to produce new plastic varieties. In order to polymerize polyolefin and polyvinyl chlorid...
