  • laminated glass has been widely used as window glass for automobiles and buildings.
  • an interlayer film for laminated glass formed by forming a plasticized polypieracetal resin such as a polyvinyl butyral resin plasticized by a plasticizer is interposed between at least a pair of glasses to be integrated.
  • Typical products are those made by Such laminated glass
  • the polyvinyl acetal is preferably a plasticized polyvinyl acetal containing 10 to 45% by weight of a plasticizer.
  • the inner layer of the multi-layer structure polymer is preferably an alkyl acrylate rubber having an alkyl group having 4 to 8 carbon atoms, or an alkyl acrylate having an alkyl group having 4 to 8 carbon atoms, if necessary. It is more preferable to contain a soft acryl-based rubbery substance obtained by copolymerizing an ester-based monomer and an aromatic vinyl monomer.
  • butyl acrylate, n-hexyl acrylate, 2-ethylhexyl acrylate, and n-octyl acrylate are preferred in terms of cost and quality.

And vinyl cyanide compounds. Of these, alkyl methacrylate is preferred from the viewpoint of copolymerizability.
  • the compounding amount of the multilayer polymer in the (plasticized) polyvinyl acetal is preferably 8 to 45% by weight, more preferably 10 to 30% by weight. If the amount is less than 8% by weight, sufficient strength cannot be obtained, and if the amount exceeds 45% by weight, the transparency of the obtained composition tends to decrease.

Abstract

L'invention porte sur une composition de résine pour verres laminés que l'on prépare en mélangeant un acétal polyvinylique plastifié avec un polymère à structure multicouche afin de ne plus avoir les inconvénients des couches d'étanchéité intermédiaires des verres laminés produits selon la technique antérieure. L'invention porte notamment sur une composition de résine pour verres laminés comprenant de 8 à 45 % en poids d'un polymère à structure multicouche et de 55 à 92 % en poids d'un acétal polyvinylique. Le polymère est composé de 40 à 85 % en poids d'une couche interne et de 60 à 15 % en poids d'une couche externe, la couche interne comprenant un caoutchouc acrylate d'alkyle et/ou un caoutchouc diène conjugué, et la couche externe étant une couche dure produite par polymérisation d'un méthacrylate d'alkyle et/ou d'un acrylate d'alkyle.
