Abstract
An article consisting of a base and one or more attachments thereto. The base is made of one thermoplastic polymer and the attachment is made of a second thermoplastic polymer which is at least partially incompatible with the first polymer. Either the first or second polymer contains 5 to 75% by weight of a third polymer which is an olefinic polymer having functional groups thereon. Either of the first two polymers may contain up to 90% of the usual additives. This enables the production of such articles with high interface strength.
