Abstract:
The present invention relates to use of a sulphur or phosphorous-containing polymer as a processing aid in a polyvinyl chloride polymer composition.

Claim (Index 1):
Use of a sulphur or phosphorous-containing polymer as a processing aid in a polyvinyl chloride polymer composition, the sulphur or phosphorous-containing polymer being used as one or both of a melt-processing additive and a flow modifier, the sulphur or phosphorous-containing polymer comprising:\n (i) residues of at least one ester-containing monomer, the ester-containing monomer(s) comprising one polymerisable carbon-carbon double bond per monomer and an ester group, and (ii) one or more residues of:\n (a) at least one monomer comprising a sulfonate, sulfonic acid, sulfonic ester, sulfonamide or sulfonyl halide group (or a salt or ester thereof), the monomer(s) comprising a sulfonate, sulfonic acid, sulfonic ester group, sulfonamide or sulfonyl halide group (or a salt or ester thereof) comprising one polymerisable carbon-carbon double bond per monomer and a sulfonate, sulfonic acid, sulfonic ester, sulfonamide or sulfonyl halide group (or a salt or ester thereof), or \n (b) at least one monomer of: \n where P is phosphorous, O is oxygen, at least one of X, Y and Z comprises at least one (and optionally only one) polymerisable carbon-carbon double bond, and at least one of X, Y and Z comprises \u2014OH, or a salt or ester thereof. the sulphur or phosphorous-containing polymer optionally being partially hydrolysed such that a proportion of said ester groups form alcohol groups, the degree of hydrolysis of the polymer being from 0 to 60 mol %.
