Polymerisable compounds, their preparation and adhesive surgical or medical dressing comprising these compounds.

摘要

Compounds of the formula:
CH2=C(R)-COO-(CH3-CH(CH3)-O)x-(CH2-CH2-O)y-OC-A-COOH
or a salt thereof, wherein
R is H or CH3,
x is an integer from 2 to 20.
y is an integer from 0 to 5,
A is an alkylene, alkenylene, or phenylene radical such that A(COOH)2 is a dibasic acid capable of forming an anhydride A(CO)2O, are described. These are polymersable compounds which have also surfactant properties. The compounds may be used to replace non-polymersible surfactants in emulsion polymerisation reactions, and preferably in those reactions which result in adhesive polymers which are suitable for surgical and medical use. Methods for preparing the compounds and pressure sensitive adhesives formed by copolymerisation of the compounds with other acrylate monomers are also described.
