AI Technical Summary
The addition of a reactive diluent to a curable composition containing a hydrolyzable silyl group-containing polyoxyalkylene polymer reduces bleed-out but decreases the recovery performance of the cured product, while increasing the modulus (modulus) leads to a decrease in flexibility.
A polyoxyalkylene polymer with terminal structures including hydrolyzable silyl groups and terminal/interior olefin groups, where the total number of these groups is more than 1.0 on average per terminal structure, and the ratio of hydrolyzable silyl groups to the total number of these groups is between 0.3 to 0.7, ensuring low modulus and high recovery performance.
The polymer achieves a cured product with low modulus and high recovery performance by balancing the number and ratio of hydrolyzable silyl and olefin groups, enhancing flexibility without compromising mechanical properties.
