O grau de polimeriza\u00e7\u00e3o do acetato de polivinilo \u00e9 normalmente de 100 a 5000. Os grupos \u00e9steres do acetato de polivinilo s\u00e3o sens\u00edveis \u00e0 hidr\u00f3lise de base e convertem lentamente o PVAc em \u00e1lcool polivin\u00edlico e \u00e1cido ac\u00e9tico. Em condi\u00e7\u00f5es alcalinas, os compostos de boro, como o \u00e1cido b\u00f3rico ou o b\u00f3rax, provocam a reticula\u00e7\u00e3o do pol\u00edmero, formando precipitados ou lama pegajosos.
\nO acetato de polivinilo \u00e9 utilizado como adesivo para materiais porosos como a madeira, o papel, o tecido e no artesanato. Tamb\u00e9m \u00e9 utilizado como prim\u00e1rio para paredes de gesso, como adesivo para papel de parede, como ingrediente formador de pel\u00edcula em tintas \u00e0 base de \u00e1gua (l\u00e1tex) e como adesivo para envelopes. \u00c9 utilizado como mat\u00e9ria-prima para a prepara\u00e7\u00e3o de outros pol\u00edmeros, como o \u00e1lcool polivin\u00edlico e o ftalato de acetato de polivinilo (PVAP). Desempenha um papel importante na lamina\u00e7\u00e3o de folhas met\u00e1licas.<\/p>","protected":false},"featured_media":4298,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[18],"product_tag":[19],"class_list":{"0":"post-4234","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-petroleum-additives","7":"product_tag-petroleum-additives","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product\/4234","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/comments?post=4234"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media\/4298"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media?parent=4234"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_brand?post=4234"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_cat?post=4234"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_tag?post=4234"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
