Abstract
The invention relates to a polymer dispersion containing water and at least 60 wt. % of an organic polymer which has at least one group of general formula (I) A—Si(Z)n(OH)3-n. The invention also relates to a composition containing at least one organic polymer which has at least one group of general formula (I), and at least one other organic polymer or a mixture of two or more other organic polymers.
Claims20
A polymer dispersion comprising water, at least 60% by weight, of the dispersion, of an organic polymer containing at least one terminal group of the formula
- —A—Si(Z)n(OH)3-n (I)
- in which A is CH2 or is a linear or branched, saturated or unsaturated alkylene radical having from 2 to about 12 carbon atoms or is an arylene radical having from about 6 to about 18 carbon atoms or an arylenealkylene radical having from about 7 to about 19 carbon atoms, Z is CH3, O—CH3 or is a linear or branched, saturated or unsaturated alkyl radical or alkoxy radical having from 2 to about 12 carbon atoms, and n is 0, 1 or 2, or a condensation product of at least two groups of the formula I and an emulsifying agent.
