Polyvinyl chloride mixed resin is to reduce the degree of polyoxyethylene resin, reduce the number of know

A special type of polyoxyethylene resin developed for use.Polyhydroethylene drainage mixed tree monitor has all

Polymer and copolymer, the particle morphology of transparent particles, spherical particles and irregular

Apparent density >, 0.6g/mL. Oil absorption rate ≤10gDOP/g

At present, there are three industrial preparation methods of vinyl chloride resin, namely float

Polymerization method, bulk polymerization method and emulsion polymerization method.Bulk polymerization is tested by atto

There are patents, generally not used, it is prepared with polyvinyl chloride mixed resin impurity particles, but

Thermal stability is not ideal.The emulsion polymerization process was used to prepare poly (ethyl chloride) explosive mixture

Fat, without centrifugal dehydration, has affinity with dioctyl phthalate, resin particle morphology

Easy to control, but difficult to prepare large particle size, strict requirements in drying, tree brain

Lots of impurity particles.As a result, most of the polyhydroethylene resin is prepared by suspension polymerization

For the.
