Abstract
Copolymerizates of methyl methacrylate and butyl methacrylate are used as plastisols in the automotive sector and as floor coverings. The invention describes a way to increase the storage stability of the plastisols by using small amounts of cross-linking agents.
Claims4
A plastisol of a copolymerizate comprising:
- (a)
- (1) 39-99% by weight if a methacrylic acid methyl ester,
- (2) 60-0% by weight of a methacrylic acid ester or an acrylic acid ester, esterified with a saturated aliphatic C2-6 straight or branched chain alcohol,
- (3) 0.1-1% by weight of a cross-linking agent or a mixture of cross-linking agents, and
- (b) 50-200% by weight of a plasticizer, based on the total amount of components (1)-(3).
