폴리(디비닐 포말) C화학적 특성, 용도, 생산
용도
It is used in the anomalous sorption and pervaporation of aqueous organic mixtures by poly(vinyl acetal) membranes. Poly(vinyl formal) is mainly used in three general applications wire coatings, surface coatings and adhesives. The first and extensive application of poly(vinyl formal) is in the manufacture of a tough, adhesive and heat resistant wire enamel.제조 방법
Poly(vinyl formal) was developed by General Electric as a wire coating and the early process involved direct reaction of a mixture of poly(vinyl acetate), glacial acetic acid, formalin and concentrated sulfuric acid at 70°C. After the desired degree of polymerization is obtained, ammonium hydroxide is added to bring the pH to about 9-10. The reaction mixture is poured into water to precipitate the poly(vinyl formal). Poly(vinyl formais) have also been used as fibers.폴리(디비닐 포말) 준비 용품 및 원자재
