Definitions
- thermoplastic polymer composition comprising the steps of (i) heating and mixing a first thermoplastic polymer composition, said composition containing a transition metal compound and having been formed by combining a heat-plastified thermoplastic polymer with a halogen-based flame retardant, and zeolite A, with a second thermoplastic polymer composition to form a heat- plastified polymer gel composition, (ii) either expressing the heat-plastified thermoplastic polymer gel composition from a die or injecting said gel composition into a mold so as to form a flame retardant article, and (iii) cooling the article to a temperature at which the article is self-supporting.
- Styrenic polymers are usually classified as general-purpose polystyrene (GPPS) or as impact modified polystyrene (IPS).
- GPPS general-purpose polystyrene
- IPS impact modified polystyrene
- GPPS is a high molecular weight, clear polymer which is hard, rigid and free of odor and taste. It finds use in producing moldings and extrusions including foams and films.
- IPS is a rubber-modified polystyrene which is characterized by its toughness and resistance to abuse. The rubber is dispersed in the polystyrene matrix in the form of discrete particles. IPS is not clear, but rather is either translucent or opaque depending upon the amount of rubber used.
- blowing agent 80 to 100% by weight of carbon dioxide and from 0 to 20%) by weight of one or more halohydrocarbons or hydrocarbons that are gaseous at room temperature
- U.S. Patents Nos. 5,189,071 and 5,189,072 wherein a preferred blowing agent is carbon dioxide and 1-chloro- 1,1-difluoroethane in weight ratios of 5/95 to 50/50
- preferred blowing agents comprise combinations of water and carbon dioxide.
- Such materials can be utilized with appropriate flame retarded thermoplastic polymer compositions of this invention.
- the invention is further illustrated by, but is not intended to be limited to, the following examples.
