Abstract (en)
[origin: WO2021079063A1] 1) Ionic silylated copolyurethane with a formula: (I) in which R1 is a hydrocarbon radical; R2 is a C2-C4 alkylene; n is an integer such that the molecular mass of -[OR2 n is 2500-20,000 g/mol; R° is H or C1-C18 alkyl; R, R' and R", are a hydrocarbon radical; x and y are integers from 1 to 8; z is an integer from 0 to 8; m and q are an integer greater than or equal to 1, such that q/m varies from 0.04 to 20; F1 is a radical with the formula (lla) and F2 is a radical with the formula (llb): (lla) (llb) in which R3 is methylene or n-propylene; R4 and R5 are a methyl or ethyl; p equals 0 or 1; R6 is a C1-C4 alkyl. 2) Method for preparing copolyurethane 1) comprising: (i) a polyaddtion between a polyisocyanate, a polyether diol and a carboxylic diol; (ii) a neutralization of the product formed with the amine N(R)(R')(R"); then (iii) a reaction with an aminosilane derived from a secondary amine. 3) Composition, usable as mastic and/or adhesive, comprising copolyurethane 1) and a filler.
