Process for polymerizing vinyl chloride with polyglycosyl polyol esters

In a process for the production of polyvinyl chloride by polymerization of vinyl chloride in an aqueous suspension in the presence of a mixture of two or more high-molecular weight surface-active agent mixture consists essentially of:

• (a) 10-90% by weight, based on the mixture of suspension agent, of an ester of a saturated or unsaturated, linear or branched carboxylic acid of 6-24 carbon atoms or a mixture thereof, and a carbohydrate having the following formula:
• ##STR5## wherein n is a number from 0 to 49 inclusive and
• R is a residue of a di- to hexahydric aliphatic, linear or branched alcohol of 2-12 carbon atoms;
• and
• (b) 90-10% by weight, based on the mixture of suspension agent, of a cellulose ether selected from the group consisting of methylcellulose, methylhydroxyethylcellulose, methylhydroxypropylcellulose, hydroxyethylcellulose, hydroxypropylcellulose or aminoethylhydroxypropylcellulose, the 2% by weight aqueous solution of the aforementioned cellulose ethers exhibiting at 20.degree. C. a viscosity of 15-50 10.sup.-3 Pa.multidot.s, or a partially saponified polyvinyl acetate with a hydrolysis degree of 69-90 mol-% and a viscosity of 2-100 mPa(s), measured in a 4% by weight aqueous solution, at 20.degree. C.
