A temperature-activated catalyst for npolyurethane or liquid polymer cures comprising the ncatalyst supported on, e.g. mounted on or bound into, a npolymer which is incompatible with, viz. insoluble in, the nreacting polymer phase. n The catalyst may contain organotin groupings and nthe polymer may be mobile or rubber and have a linear npolymer backbone , e.g. styrene-allyl alcohol. n The polymer may be glassy and be ground to a nfine powder. |
