PROCESS FOR PRODUCTION OF POLYURETHANE FOAM USING TETRAALKYLSTANNOXY BASED CATALYST Russian patent published in 2018 - IPC C08G18/24 C08G18/18 C08G18/48 C08G101/00 

Abstract RU 2652984 C2

FIELD: manufacturing technology.

SUBSTANCE: present invention relates to a process for the preparation of a product from polyurethane foam. Method comprises forming products from polyurethane elastomers, obtained by reacting a polyisocyanate component and a polyol component in the presence of a tetraalkylstannoxy based catalyst of formula

,

in which R is C9-C11 alkyl.

EFFECT: use of said catalysts to produce polyurethane products enables to obtain a product having increased fatigue under repeated deformations, and also provides a shorter moulding time.
