As a main component of a building sealing material, for example, a hydrolyzable silyl group-containing isobutylene-based polymer is used, and the isobutylene-based polymer contains a hydrolyzable silyl group at both ends of the molecule and is generally used in water and air. Curing occurs due to the hydrolysis reaction by the moisture (moisture) (having moisture curability). However, since the position of the hydrolyzable silyl group (eg, alkoxysilyl group) is controlled at the molecular end of this isobutylene polymer, the physical properties of the cured product are good, but the molecular weight of the side chain is large and the polypropylene A rigid main chain, which is a C—C bond that does not have an ether bond, such as an oxite chain, has a high viscosity, which causes stringing when the sealing material is applied (spinability).
Work efficiency is poor due to dripping or drooping.
The use of a plasticizer may be considered for this improvement, but if used in a large amount, the surface residual tack and the rubber elasticity are deteriorated, and further, the polymer content is lowered and the weather resistance is lowered.
