Abstract

The invention discloses a functional modifier of styrene and polyvinyl chloride and relates to the field of thermoplastic modified aids for compatible copolymerization of styrene and polyvinyl chloride. At present, a modifier of the class does not exist in China. The modifier is a high polymer prepared by polymerizing the following raw materials in a reaction kettle in parts by weight: 18-22 parts of styrene, 8-11 parts of diethyl maleate, 16-20 parts of fumaric acid and 60-65 parts of chloroethylene. The preparation method comprises the following steps of: weighing corresponding raw materials according to the parts by weight of the raw materials; putting the raw materials in the reaction kettle; uniformly stirring and heating to 45-65 DEG C; and reacting for 3 hours to obtain the functional modifier of the styrene and the polyvinyl chloride. The functional modifier is used as a thermoplastic functional modifier compatibly copolymerized by the styrene and the polyvinyl chloride, and when the styrene and the polyvinyl chloride are polymerized, the functional modifier is added, which can ensure that the styrene and the polyvinyl chloride are compatibly polymerized. New plastic cement formed by polymerizing has high quality and excellent heat resistance, flame retardance and plasticization processing property.

Description

technical field [0001] The invention relates to the field of thermoplastic modification additives for compatible copolymerization of styrene and polyvinyl chloride, in particular to a functional modifier for compatible copolymerization of styrene 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 research the polymerization of styrene (ABS resin, its full name is acrylonitrile___butadiene___styrene resin) with polyvinyl chloride to produce new Plastic varieties. However, styrene and polyvinyl chloride are incompatible and difficult to polymerize, so it is impossible to polymerize styrene and polyvinyl chloride into new plastic varieties. In order to polymerize styrene and polyvinyl chloride...
