Rigid polyvinyl chloride containing reduced amounts of titanium dioxide and a tin mercaptide thermal stabilizer, said polyvinyl chloride being stabilized against the adverse effects of ultraviolet radiation by the addition thereto of effective amounts of benzoate compounds.

Benzoate-stabilized rigid polyvinyl chloride compositions

An improved process for terminating the suspension polymerization reaction of vinyl chloride monomer into polyvinyl chloride which comprises adding hindered phenols of the structure presented hereinafter to the polymerization reaction at a point in time when a predetermined amount of monomer conversion has occurred.

Substituted phenol chain terminator for polyvinyl chloride polymerization

Rigid polyvinyl chloride containing reduced amounts of titanium dioxide and a tin mercaptide thermal stabilizer, said polyvinyl chloride being stabilized against the adverse effects of ultraviolet radiation by the addition thereto of effective amounts of mono- and dibenzoate compounds.

Tri-N-substituted-s-triazine-trione chain terminator for polyvinyl

Hindered phenolic esters of oligomeric glycols as chain terminators for

Fiber finish compositions comprising a major amount of a polyoxyalkylene glycol or fatty acid ester lubricant and a minor amount of an oxidative and thermal stabilizer system therefor comprising a blend of a substituted 1,3,5-triazine and a multi-functional hindered phenolic compound, a process for the application thereof and the coated fibers resulting therefrom.
