Abstract

1472881 Foamed plasticized sulphonated polymers EXXON RESEARCH & ENG CO 20 March 1974 [29 March 1973] 12308/74 Heading C3C A foamed polymer having a uniform cell structure is made by mixing at a temperature of at least 40‹ C. and a pressure of more than 6 p.s.i. above atmospheric a foaming agent comprising a compound having a solubility parameter of less than 7À9 and more than 4À5 an ionic polymer having 0À2-20 mole per cent of sulphonic acid groups neutralized to a degree of at least 90% with a neutralizing agent which is ammonia, a C 1-30 amine, a basic compound whose cation is a metal of Groups Ia, IIa, Ib or IIb of the Mendeleeff Periodic Table of Elements, lead, tin, antimony or aluminium, and a non- volatile polar compound having a dipole moment of at least 0À9 debyes, of b.p. greater than 150‹ C. at atmospheric pressure and which is a preferential plasticizer for the pendant ionic groups of the polymer (i.e. having no effect on the non-ionic portion of the polymer), whereby the plasticizer is incorporated into the polymer which is then foamed. The foamed polymer has a density of less than 10 lb/foot<SP>3</SP>, an average cell volume of less than 0À3 x 10<SP>-3</SP> cm.<SP>3</SP>, and less than 5% of the foamed volume is occupied by cells of volumes greater than 0À5 x 10<SP>-2</SP> cm.<SP>3</SP> In the examples sulphonated polystyrenes, which were 100% neutralized and had sodium or barium as the cation, were mixed with the above polar compound, viz. phenethanol, pentaerythritol, 3,4-dimethyl benzoic acid or decanol, moulded into a pad and immersed in dichlorodifluoromethane, isopentane, butane, pentane or 1,1,2 - trichlorotrifluoro - ethane under elevated temperature and pressure, and then the impregnated polymer was foamed by heating in silicone oil or by exposure to microwave radiation. The ionic polymer may also be a sulphonated styrene/ t-butyl styrene copolymer and an adipate, citrate, glycolate, laurate, oleate, palmitate, phthalate, phosphate or sebacate may also be used as a chain-plasticizer.
