Abstract

1484087 Heat stabilizer/blowing agent activator for vinyl chloride polymers M & T INTERNATIONAL BV 23 Oct 1974 [25 Oct 1973] 45865/74 Heading C3C A composition for the preparation of cellular vinyl chloride polymers comprises: (i) 100 parts by weight of a vinyl chloride homopolymer or a copolymer of vinyl chloride with up to 50% by weight of at least one copolymerizable ethylenically unsaturated monomer; (ii) 0.1-10 parts by weight of a heat decomposable blowing agent; (iii) 0.1-10 parts by weight of a combined blowing agent activator and heat stabilizer which comprises: (I) 5-99% by weight of a diorganotin compound of formula (II) 1-95%, by weight, based on component (I), of an auxiliary activator-stabilizer selected from organo tin compounds of the general formula wherein R<SP>1</SP> represents C 1-18 alkyl, R<SP>2</SP> represents C 4-18 alkyl or R<SP>1</SP> and R<SP>2</SP> are cycloalkyl, aryl, alkaryl or aralkyl, each of which contain 6-18 carbon atoms, R<SP>3</SP> is R<SP>1</SP>, X represents a radical selected from wherein R<SP>4</SP> represents C 1-12 alkylene, C 6-12 arylene, or aralkylene, R<SP>5</SP> and R<SP>6</SP> are R<SP>2</SP>, R<SP>7</SP> represents the residue resulting from the removal of the hydrogen atom(s) from the hydroxyl group of a phenol or an alcohol, said alcohol being C 2-18 and comprising 1-4 hydroxyl radicals and R<SP>8</SP> represents and a is 1 or 2. Additionally the blowing agent may be di-n-butyltin laurate, monobutyltin tris (n-dodecyl maleate), di-n-butyltin bis-(isooctyl maleate), di-n-butyltin di-n-butoxide or zinc octenoate. Preferred copolymers are vinyl chloride with at least one of vinyl acetate, vinylidene chloride, ethylene, acrylonitrile and esters of acrylic or methacrylic acids whilst the preferred blowing agents are azobisformamide and p-toluenesulphonylsemicarbazide. The examples illustrate different combinations of stabilizer activator with blowing agents and a specific formulation consisted of polyvinylchloride, calcium carbonate, an acrylic polymer processing aid, acrylonitrile/butadiene styrene terpolymer, titanium dioxide, azobisformamide, paraffin wax, calcium stearate and, as stabilizer di - n - butyltin - S,S<SP>1</SP> - bis - (isooctylmercaptoacetate), or Ba/Cd carboxylates as controls, and 90 : 10 weight ratio of di-n-butyltin- S,S<SP>1</SP> - bis - (tri - n - decylmercaptide) and di - nbutyltin dilaurate as illustrating the invention.
