Abstract
PURPOSE: To provide multilayer glass capable of holding a fixed shape over a long period without deforming spacers during storage by putting a plurality of glass plates one over another at spaces with spacers contg. partially vulcanized butyl rubber.
CONSTITUTION: A desiccating substance such as synthetic crystalline zeolite or activated alumina, a viscosity imparting agent, a filler, etc. are added to base rubber such as polyisobutylene or polybutene contg. 15W40 wt% of partially vulcanized butyl rubber with a partial vulcanization degree corresponding to a gelation ratio of 5W90% and a MW of 300000W500000. They are then kneaded and extrusion molded into a predetermined spacer sectional size. Using the resulting flexible self-viscous rubbery spacers whose moisture permeability at 40°C and 90% RH is 0.05W2.0 g/m2.24hr.mm or below, a plurality of glass plates are put one over another at spaces.
